Section 2 TSP Programming Fundamentals In this section: Introduction ....................................................................... 2-1 Test Script Processor (TSPTM) ........................................ 2-2 Run-time environment ....................................................... 2-3 Queries ............................................................................. 2-3 Scripts ............................................................................... 2-4 Named scripts ...............
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Test Script Processor (TSPTM) The Test Script Processor (TSP) is a scripting engine that runs inside the instrument. It is capable of running code written in a scripting language called Lua (http://www.lua.org). This makes the instrument fully capable of interpreting and executing code in a way that is similar to Visual Basic (VB) or Java, rather than only responding to single-line commands.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Run-time environment A feature of all scripting environments is the run-time environment. In the TSPTM, the run-time environment is simply a temporary collection of global variables. A global variable can be used to remember a value as long as the unit is powered on and the variable is not assigned a new value.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Scripts When taking advantage of the TSPTM to perform more complicated sequences of commands, especially sequences utilizing advanced scripting features such as looping and branching, sending the entire sequence in one message is very cumbersome. Use the loadscript and endscript messages to collect a sequence of commands into one chunk. The loadscript message marks the beginning of a script.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Named scripts The loadscript message can also be used to create named scripts. Loading a named script does not replace the anonymous script. Instead, a global variable in the run-time environment is temporarily created to store the script. Because the script is stored in a global variable, the name of the script must be a legal TSL variable name.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Programming overview Chunk defined A chunk is a single programming statement or a sequence of statements that are executed sequentially (that is, sent to Lua as a single line). There are nonscripted and scripted chunks.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Script defined The Series 3700 utilizes a Test Script Processor (TSP) to process and run individual chunks or scripts. A script is a collection of instrument control commands and programming statements. The TSP test script example (on page 2-7) shows an example of how to create and load a script.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Run-time environment The run-time environment is a collection of global variables (scripts) that you have created. After scripts are placed into the run-time environment, they are then ready to be run and/or managed.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Programming model for scripts User-created scripts can be stored in nonvolatile memory. When the Series 3700 is turned on, all user script functions are recalled into the run-time environment from nonvolatile memory. If any user scripts have been programmed to run automatically, they will run after all the scripts are loaded.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Installing the TSPTM software To install the TSP software: 1. Close all programs. 2. Place the CD (Keithley Instruments part number KTS-850B01 or greater) into your CD-ROM drive. 3. Follow the on-screen instructions. If your web browser does not start automatically and display a screen with software installation links, open the installation file (index.html) found on the CD to initiate automatic installation.

Connect one end of the cable to the host computer and the other end to Series 3700.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual GPIB address At the factory, the GPIB is set to address value 16. The address value can be set to any address value between 0 and 30. However, the address cannot conflict with the address assigned to other instruments in the system. Change the GPIB address from the GPIB menu. To access the menu, press the MENU key and select GPIB. The GPIB address is saved in nonvolatile memory.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals USB connection Connect a computer controller to the Series 3700 rear panel USB (from host) connector (connect USB flash drive devices to the Series 3700 front panel USB). Refer to Rear panel summary (on page 2-10) for connector location. NOTE For your Series 3700 to be recognized by your computer over the USB interface, the proper driver must be installed.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Figure 2-5: Using Test Script Builder (TSB) Project Navigator The Project Navigator resides in the window pane on the left side of the workspace. The navigator consists of project folders and the script files (.tsp) created for each project. Each project folder can have one or more script files.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Programming interaction Up to seven tabs can be displayed in the lower pane of the workspace (the script editor) to provide programming interaction between the Test Script Builder and the Series 3700. The instrument console shown in Using Test Script Builder (TSB) (on page 2-13) is used to send commands to the connected Series 3700.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Read and write to the digital I/O port The digital I/O port of the Series 3700 is used to control external circuitry (such as a component handler for binning operations). The I/O port has 14 input/output bits (lines) that can be at TTL logic state 1 (high) or 0 (low). See the pinout in the graphic in Rear panel summary (on page 2-10) for the Digital I/O port for additional information.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Script examples Script using commands and statements only The following script closes Channels 1-10 on Slot 3 and measures voltage on each channel. The ten voltage readings are returned to the host computer, as well as being stored in a voltage table on the instrument, using the channel numbers as keys to index the table.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Script using a function TSL facilitates grouping commands and statements using the function keyword. Therefore, a script can also consist of one or more functions. Once a script has been run, the host computer can then call a function in the script directly.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Interactive script An interactive script prompts the operator (on the Series 3700 display) to input test parameters (using the Series 3700 front panel). The chunk fragment in the following table uses display messages to prompt the operator to select a measure function (DCV or 2-wire) and a range based on function, and to input the measurement speed.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Creating a user script To create a script and load it, the test program (chunk) must be framed by the following shell commands: loadscript or loadandrunscript, and endscript. Load only The following scripts will load only into the run-time environment of the Series 3700.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals A script saved in nonvolatile memory named autoexec has special properties that cause it to run automatically after the Series 3700 is powered on and all autorun scripts have been executed. For details, see Autoexec script (on page 2-26) and Autorun scripts (on page 2-26). loadandrunscript loadsandrunscript name Where: name is the user-assigned name for the script.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Get or change the name attribute of a script The following commands are used to get or change the name attribute of a script: val = myscript.name -- read the name of myscript myscript.name = val -- change the name of myscript Where: myscript is the script val is the name of the script This attribute may optionally be initialized when the script is created. See Loading a user script (on page 2-24) (script.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Saving a named script Only a named script can be saved in nonvolatile memory of the Series 3700. After creating and loading a named script, use one of the following commands to save it. myscript.save() -- To save script in internal memory myscript.save('filename') -- To save script on flash drive Where: myscript is the user-defined name of the script.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual The anonymous script may be saved to the flash drive without setting the name attribute. For example, to save the anonymous script on the flash drive as "MyAnonTest.tsp": script.anonymous.save('/usb1/MyAnonTest.tsp') Loading this file ('MyAnonTest.tsp') back into the unit from the flash drive will cause an existing anonymous script to be overwritten.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals To execute the myuserlist script: script.user.scripts.myuserlist() mylist() Running a user script Running an unnamed script There can only be one unnamed (anonymous) script in the run-time environment. If another anonymous script is created and loaded, the previous anonymous script will be removed from the run-time environment. On the front panel, an unnamed script appears as .
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Autorun scripts When a saved script is set to autorun, it will automatically load and run when the Series 3700 is turned on. Any number of scripts can be set to autorun. The run order for these scripts is arbitrary, so make sure the run order is not important. To set a script for autorun, set one of the following autorun attributes to "yes." Setting it to "no" disables autorun. myscript.autorun script.user.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Running a user script from the Series 3700 front panel Use the following commands to enter or delete a name in the User menu option from the LOAD key: display.loadmenu.add(displayname, chunk) display.loadmenu.delete(displayname) Where: displayname is the name to be added to (or deleted from) the User menu. chunk is the name of the chunk (Lua executable code).
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Loading a script from the Series 3700 front panel To load a script from a USB flash drive: 1. Press the MENU key to open the main menu. 2. Select the SCRIPT option. 3. Select the LOAD option. A menu is displayed that includes the USB option. 4. Select the USB option. A menu is displayed that lists the .tsp files and directories on the flash drive.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Saving a script from the Series 3700 front panel To save a script to internal memory or a USB flash drive: 1. Press the MENU key to bring up the Main Menu. 2. Select the SCRIPT option. 3. Select the SAVE option to bring up a menu listing the scripts available to save from the script.user.scripts table. This may take several seconds before displaying. 4. Select the script that you want to save.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Script management Retrieving a user script You can retrieve the source code contained in a user script from nonvolatile memory, which can then be modified and saved as a user script under the same name or a new name. NOTE You can load a modified user script into the Series 3700 using the same name or a new name.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Deleting a script from the system To completely remove a script from the system, all references to the script will need to be deleted from the run-time environment. A script may be removed from the run-time environment by assigning it to nil.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Differences: Remote versus local state The Series 3700 can be in either the local state or the remote state. When it is in the local state (REM annunciator off), the instrument is operated using the front panel controls. When it is in the remote state (REM annunciator on), instrument operation is controlled by the computer. When the instrument is powered-on, it is in the local state.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Stand-alone system A script can be run from the front panel of any node (instrument) in the system. When a script is run, all nodes in the system go into remote operation (REM annunciators turn on). The node running the script becomes the primary node and can control all of the other nodes, which become its subordinates.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Variables and types TSL has six basic types: nil, boolean, number, string, function, and table. TSL is a dynamically typed language, which means variables do not need to be declared as a specific type. Instead, variables assume a type when a value is assigned to them. Therefore, each value carries its own type. If a variable has not been assigned a value, the variable defaults to the type nil.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Relational operators: < (less than) > (greater than) <= (less than or equal) >= (greater than or equal) ~= (not equal) == (equal) Logical operators: and or not Functions TSL allows you to define functions which can take a pre-defined number of parameters and return multiple parameters.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual This function returns multiple parameters (sum, difference, and ratio of the two numbers passed to it): function sum_diff_ratio(parameter1, parameter2) psum = parameter1 + parameter2 pdif = parameter1 – parameter2 prat = parameter1 / parameter2 return psum, pdif, prat end sum, diff, ratio = sum_diff_ratio(2,3) print(sum) print(diff) print(ratio) The function's output is: 7 12 5 -1 0.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Tables can be indexed using element names instead of numeric indices. Because functions are first-class variables, tables can be used to create "pseudoclasses." Classes are often used in object-oriented programming. Below is a table used to create a circle pseudoclass.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual or All operators are left associative, except for "^" (exponentiation) and "..", which are right associative. Therefore, the following expressions on the left are equivalent to those on the right: a+i < b/2+1 (a+i)< ((b/2)+1) 5+x^2*8 5+((x^2)*8) a < y and y <= z (a < y) and (y <= z) -x^2 -(x^2) x^y^z x^(y^z) Logical operators The logical operators are and, or, and not.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals For example, it sets x to a default value v when x is not set (provided that x is not set to false).
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Branching TSL uses the if keyword to do conditional branching. ---------------- IF blocks ----------------- This is if expression 1. Zero is true in Lua language; this is a contrast to C language, where 0 evaluates false. In TSL, nil is false and everything else is true. if 0 then print("Zero is true!") else print("Zero is false.") end x = 1 y = 2 -- This is if expression 2.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Output of code above: Zero ' if ' if ' if x is is true! ' expression ' expression ' expression not equal to 2 was not false. 3 was not false. 4 was false. 10, and y is not less than 2. Loop control TSL has familiar constructs for doing things repetitively or until an expression evaluates to false.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual ---------------- REPEAT loop ---------------print("Counting elements in list") print("using repeat") element = 1 repeat print(element, list[element]) element = element + 1 until not list[element] Output of code above: Counting from one 1 One 2 Two 3 Three Counting from one in steps of two: 1 One 3 Three Counting elements on numeric index 1 One 2 Two 3 Three 4 Four 5 Five 6 Six Counting elements using repeat 1 One
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Base library functions print(x) Prints the argument x to the active host interface, using the tostring() function to convert x to a string. collectgarbage([limit]) Sets the garbage-collection threshold to the given limit (in Kbytes) and checks it against the byte counter. If the new threshold is smaller than the byte counter, then TSL immediately runs the garbage collector.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual String library functions This library provides generic functions for string manipulation, such as finding and extracting substrings. When indexing a string in TSL, the first character is at position 1 (not 0 as in ANSI C). Indices may be negative and are interpreted as indexing backward from the end of the string. Thus, the last character is at position 1, and so on.
Series 3700 System Switch/Multimeter Reference Manual Section 2: TSP Programming Fundamentals Math library functions This library is an interface to most of the functions of the ANSI C math library. All trigonometric functions work in radians. The functions math.deg() and math.rad() convert between radians and degrees. Function Definition math.abs(x) Returns the absolute value of the argument x. math.acos(x) Returns the principal value of the trigonometric arc cosine function of x. math.
Section 2: TSP Programming Fundamentals Series 3700 System Switch/Multimeter Reference Manual Function Definition math.frexp() Splits x into a fraction f and exponent n, such that f is 0.0 or 0.5 <= | f | <= 1.0, and f * 2n is equal to x. Both f and n are returned: f,n = math.frexp(x). math.ldexp(x, n) Returns the inverse of the math.frexp() function; it computes the value x * 2n. math.random([x],[ y]) When called without an argument, returns a pseudo-random real number in the range [0, 1].

Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual Figure 3-1: Multiple TSP-Link networks 3-2 3700S-901-01 Rev.
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features The second method to run parallel test scripts is to use groups with a single TSP-Link network. A group consists of one or more nodes with the same group number. Each group on the TSP-Link network can run different test scripts at the same time (in parallel). The following figure displays a TSP-Link network with groups. This method requires one TSP-Link network and a single GPIB connection to the PC.
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual The following table describes the functions of a single TSP-Link network. Each group in this example runs multiple test scripts at the same time or in parallel (see the previous figure).
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features Master node overview The master node is always the node that coordinates activity on the TSP-Link network. All nodes assigned to group 0 belong to the same group as the master node.
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual Reassigning groups Use the following code to change group assignment. You can add or remove a node to a group at anytime. -- Assigns the node to a different group. node[N].tsplink.group = G Running parallel test scripts You can issue the execute command from the master node to initiate test script and TSL code on a remote node. The execute command places the remote node in the overlapped operation state.
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features Coordinating overlapped operations in remote groups Errors occur if you send a command to a node in a remote group running an overlapped operation. All nodes in a group must be in the overlapped idle state before the master node can send a command to the group.
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual Using the data queue for real-time communication You cannot access the reading buffers or global variables from any node in a remote group while a node in that group is performing an overlapped operation. You can use the data queue to retrieve data from any node in a group performing an overlapped operation. In addition, the master node and the group leaders can use the data queue as a way to coordinate activities.
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features Removing stale values from the reading buffer The node that acquires the data stores the data for the reading buffer. To optimize data access, all nodes can cache data from the node that stores the reading buffer data. Running TSL code remotely can return stale values from the reading buffer to the cached data.
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual Commands related to TSP advanced features dataqueue.add() Function Store an item of data in the data queue. Usage success = dataqueue.add(value[, timeout]) value: The data item to add. timeout: Maximum amount of time in seconds to wait for room in the queue if it is full. success: Success indication. Remarks This function will add one entry to the data queue.
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features dataqueue.count Remarks This attribute is a read-only attribute that indicates how many entries are in the data queue. dataqueue.next() Function Retrieve an entry from the data queue. Usage value = dataqueue.next([timeout]) timeout: Maximum amount of time in seconds to wait for data if the queue is empty. value: The next entry from the data queue.
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual localnode.getglobal() Remarks This function will return the value of the given global variable. This function is provided to allow code running on a remote master node to retrieve values of variables from that node. This function should not be used to retrieve the value of a global variable on the local node when using the local node as the master. Accessing the variable directly is far more efficient.
Series 3700 System Switch/Multimeter Reference Manual Section 3: TSP Advanced Features tsplink.trigger[N].assert() Function Simulates the occurrence of the trigger and generates the corresponding event id. Usage tsplink.trigger[N].assert() N: The trigger line to assert (1–3). Remarks This function will generate a trigger pulse on the given TSP-LinkTM trigger line. Also see tsplink.trigger[N].clear() (on page 3-13) tsplink.trigger[N].mode (on page 3-13) tsplink.trigger[N].
Section 3: TSP Advanced Features Series 3700 System Switch/Multimeter Reference Manual tsplink.trigger[N].mode Remarks This attribute controls the mode in which the trigger event detector as well as the output trigger generator will operate on the given trigger line. mode can be one of the following values: tsplink.TRIG_BYPASS Allow direct control of the line. tsplink.TRIG_EITHER Detect rising or falling edge triggers as input. Assert a TTL-low pulse for output. tsplink.

Series 3700 System Switch/Multimeter Reference Manual Section 5: Range, Digits, Rate, Bandwidth, and Filter Rate The RATE key sets the integration time (measurement speed) of the A/D converter. This controls how long the input signal is measured (also known as aperture). The integration time affects the amount of reading noise, as well as the ultimate reading rate of the instrument. The integration time is specified in parameters based on a number of power line cycles (NPLC), where 1 PLC for 60Hz is 16.
Section 5: Range, Digits, Rate, Bandwidth, and Filter Series 3700 System Switch/Multimeter Reference Manual The front panel RATE settings for all but the AC functions are explained as follows: FAST sets integration time to 0.1 PLC. Use FAST if speed is of primary importance (at the expense of increased reading noise and fewer usable digits). MEDium sets integration time to 1 PLC. Use MEDium when a compromise between noise performance and speed is acceptable. SLOW sets integration time to 5 PLC.
Series 3700 System Switch/Multimeter Reference Manual Section 5: Range, Digits, Rate, Bandwidth, and Filter Setting Rate from the front panel The RATE key is used to set measurement speed from the front panel.

For remote programming, the integration rate can be set from 0.0005PLC to 12PLC or 15PLC. To achieve the best accuracy for ACV and ACI measurements, use the bandwidth setting that best reflects the frequency of the input signal.
Series 3700 System Switch/Multimeter Reference Manual Section 5: Range, Digits, Rate, Bandwidth, and Filter Moving average filter The moving average filter uses a first-in first-out stack, where the newest reading conversion replaces the oldest. An average of the stacked reading conversions yields a filtered reading. After the specified number of reading conversions ("Filter count") fill the stack, the moving filter gives a new reading for every new conversion.
Section 5: Range, Digits, Rate, Bandwidth, and Filter Series 3700 System Switch/Multimeter Reference Manual Digital filter window The digital filter uses a "noise" window to control the filter threshold. As long as the input signal remains within the selected window, A/D conversions continue to be placed in the stack. If the signal changes to a value outside the window, the filter resets and starts processing again, starting with a new initial conversion value from the A/D converter.

Section 7: Buffer: Data Storage and Retrieval Series 3700 System Switch/Multimeter Reference Manual Dynamic buffer programming example The programming example below shows how to store data using a dynamicallyallocated buffer named mybuff. -- Reset the DMM. dmm.reset('all') -- Create a buffer named mybuffer and allocate space for 100,000 readings. mybuffer = dmm.makebuffer(100000) -- Enable append buffer mode. mybuffer.appendmode = 1 -- Set count to 1. dmm.
Series 3700 System Switch/Multimeter Reference Manual Section 7: Buffer: Data Storage and Retrieval Buffer for...do loops The following examples illustrate the use of for...do loops with respect to recalling buffer data from a reading buffer called mybuffer. The following code may be sent as one command line or as part of a script. Sample outputs follow the line of code. Also see the printbuffer() (on page 13-221) ICL command. NOTE Buffer mybuffer has time stamp collection enabled in the example below.
Section 7: Buffer: Data Storage and Retrieval Series 3700 System Switch/Multimeter Reference Manual The following loop uses the print command instead of the printbuffer command. This loop shows the same information described in the previous example (reading, units, and relative time stamps for all readings stored in the buffer).

Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Channel assignments Each switching module has a certain number of channels. For example, the Model 3720 switching module has 60 channels (1 through 60). When you encounter a 1- to 3-digit channel number in this manual, the switching module channel is the point of discussion. A 4-digit channel number includes the slot number followed by the 3-digit channel number.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Event blenders Advanced event handling requires a way to wait for one of several events (or all of several events). An event blender provides for this combining or blending of events. An event blender can combine up to four events in either an "or" mode or an "and" mode. When in "or" mode, any one of the input events will cause an output event to be generated.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Trigger model The following flowchart represents a trigger model implemented in the Series 3700. The trigger model is used during a scan only. For front panel operation, you use the SCAN and STEP keys to perform scan actions. For remote operation, you use the scan functions and attributes commands, for example, scan.execute() and scan.mode. Figure 8-2: Trigger model 8-4 3700S-901-01 Rev.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning The Series 3700 trigger model has the following events and associated ICL command attributes. These events, along with other events in the system, may be used to configure various stimulus settings. For example, the channel ready event (scan.trigger.EVENT_CHANNEL_READY) may be set to pulse digital I/O line 3 when it gets generated. The command message for this would be: digio.trigger[3].stimulus = scan.trigger.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Triggers The following four action triggers are associated with the trigger model operation: Arm Action Trigger Channel Action Trigger (this trigger may be bypassed for the first channel of the first scan count) Sequence Action Trigger Measure Action Trigger STEP operation: When the trigger event is detected, a channel is closed and a measurement may be taken, if it is configured for one.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Stimulus Description Measure Action Trigger Affects the "Wait Measure Trigger" block of the trigger model. This trigger is associated with the ICL scan.trigger.measure.stimulus (on page 13-247). Scan and step counts When running a scan, it may be necessary to determine the scan progress. Use scan and step count to determine the point in the scan table being executed.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual 5. The trigger model leaves the idle state and opens channels involved in scanning, along with channels that would interfere with scanning, such as AMP channels, analog backplane relays 1 and 2 on all slots, common-side ohm backplane channels, and other channels in banks involved in scanning.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Buffer To recall scanned readings stored in the buffer, press the REC key and turn the navigation wheel to navigate through the buffer. See Recalling readings (on page 7-5) for details on recalling buffer readings. When finished, make sure to exit from buffer recall (press the EXIT key). Also see Buffer: Data Storage and Retrieval (on page 7-1).
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual The ICL commands to simulate this example follow. Assume the Model 3720 is in Slot 3: -- Configure Channels 1 to 60 to measure DC volts. dmm.setconfig('slot3', 'dcvolts') -- Create a scan list, channels measuring DC volts. scan.create('slot3') -- View the scan list, 60 channels measuring DC volts. print(scan.list()) -- Change Channels 1 to 30 to 4-wire ohms. dmm.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning When removing channels, channel patterns will not be checked to determine if the channel being removed is associated with its image. To remove a channel pattern in a scan list, select the channel pattern to be removed, and then press the DELETE key.

Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Output characteristics: The trigger.assert command generates a low pulse for the programmed pulse duration. Rising edge master trigger mode (version 1.4.0 or higher) Use the rising edge master trigger mode (RisingM) to synchronize with non-Keithley Instruments that require a high pulse. Input trigger detection is not available in this trigger mode. You can use the RisingM trigger mode to generate rising edge pulses.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Rising edge acceptor trigger mode (version 1.4.0 or higher) The rising edge acceptor trigger mode (RisingA) generates a low pulse and detects rising edge pulses. The following graphic displays the RisingA input trigger. Figure 8-6: RisingA input trigger Input characteristics: All rising edges generate an input event. Figure 8-7: RisingA output trigger 8-22 3700S-901-01 Rev.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Output characteristics: The trigger.assert command generates a low pulse that is similar to the falling edge trigger mode.

Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Input characteristics: All rising or falling edges generate an input trigger event Figure 8-9: Either edge output trigger Output characteristics: The trigger.assert command generates a low pulse that is similar to the falling edge trigger mode.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Synchronous master trigger mode Use the synchronous master trigger mode (SynchronousM) to generate falling edge output triggers, to detect the rising edge input triggers, and to initiate an action on one or more external nodes with the same trigger line. In this mode, the output trigger consists of a low pulse.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Input characteristics: All rising edges are input triggers. When all external drives release the physical line, the rising edge is detected as an input trigger. A rising edge cannot be detected until all external drives release the line and the line floats high. Figure 8-11: SynchronousM output trigger Output characteristics: The trigger.
Series 3700 System Switch/Multimeter Reference Manual Section 8: Scanning Synchronous acceptor trigger mode Use the synchronous acceptor trigger mode (SynchronousA) in conjunction with the SynchronousM trigger mode. The role of the internal and external drives are reversed in the SynchronousA trigger mode.
Section 8: Scanning Series 3700 System Switch/Multimeter Reference Manual Synchronous trigger mode The synchronous trigger mode is a combination of SynchronousA and SynchronousM trigger modes. Use the synchronous trigger mode for backwards firmware compatibility. The SynchronousA and SynchronousM trigger modes provide additional flexibility. It is recommended that you use SynchronousA and SynchronousM for firmware v1.4.0 or higher, and use the synchronous trigger mode for firmware prior to v1.4.0.

Section 9: Files Series 3700 System Switch/Multimeter Reference Manual File system navigation The Lua FS library provides the command set necessary to navigate the file system and list the available files on a flash drive. The instrument encapsulates this command set as an fs logical instrument, so that the file system of any given node is available to the entire TSP-LinkTM system. For example, the command node[5].fs.readdir(".") can be used to read the contents of the current working directory on Node 5.
Series 3700 System Switch/Multimeter Reference Manual Section 9: Files File I/O Lua supports file I/O with its io library commands. A subset of these commands is supported for use with Series 3700 instruments. As with Lua FS, these commands are encapsulated as an io logical instrument so that the files on any given node are accessible to the entire TSP-LinkTM system. Lua organizes its file I/O commands into two groups: Commands that reside in the io table, for example: io.open, io.close, io.input, and io.
Section 9: Files Series 3700 System Switch/Multimeter Reference Manual io.type (on page 9-14) (supported on the local node only when the Series 3700 is a master) The following standard I/O commands are not supported at this time: file:lines file:setvbuf io.lines io.popen io.tmpfile Script examples The following script will open three different files to help illustrate the differences between the io commands and file descriptor commands.

Section 10: TSP-Net Series 3700 System Switch/Multimeter Reference Manual Using TSP-NetTM with any Ethernet-enabled device NOTE Refer to the Instrument Control Library (ICL) (on page 12-1) for more details on the commands presented in this section. To communicate to a remote Ethernet-enabled device from the Series 3700, perform the following steps: 1. Connect to the remote device through the LAN port. Use an Ethernet crossover cable to connect directly from the Series 3700 to an Ethernet-enabled device.
Series 3700 System Switch/Multimeter Reference Manual Section 10: TSP-Net Example script The following example demonstrates how to connect to a remote non-TSPTMenabled device, and send and receive data from this device: -- Disconnect all existing TSP-NetTM connections. tspnet.reset() -- Set tspnet timeout to 5 seconds. tspnet.timeout = 5 -- Establish connection to another device with IP address 192.168.1.51 at port 1394. id_instr = tspnet.connect("192.168.1.
Section 10: TSP-Net Series 3700 System Switch/Multimeter Reference Manual Using TSP-NetTM vs. TSP-LinkTM for communication with TSP-enabled devices TSP-Link is the preferred communication method when communicating between the Series 3700 and another TSPTM-enabled instrument. Using TSP-Link has certain advantages over using TSP-Net, including: Error checking: When connected to a TSP-enabled device, all errors that occur on the remote device are transferred to the error queue of the Series 3700.

Section 11: LXI Class B Triggering (IEEE-1588) Series 3700 System Switch/Multimeter Reference Manual At periodic intervals, the master clock synchronizes to all slave clocks through time-stamped messages over the PTP port. This allows IEEE-1588 to maintain time synchronization between multiple devices on a network. Program the synchronization interval in the Series 3700 using ptp.syncinterval (on page 13-229). The default synchronization interval is two seconds.
Series 3700 System Switch/Multimeter Reference Manual Section 11: LXI Class B Triggering (IEEE-1588) You can avoid confusion by setting the time on the Series 3700 to UTC time instead of local time. Manage the conversion from UTC to local time in your software application. For example, assume local time is Eastern Standard Time in the United States (EST), which is equivalent to GMT-5 (hours). Therefore, if the current local time is 3:00PM, the UTC time is 8:00PM.
Section 11: LXI Class B Triggering (IEEE-1588) Series 3700 System Switch/Multimeter Reference Manual Use ptp.enable() (on page 13-227) to enable IEEE-1588 on the Series 3700. The IEEE-1588 protocol then determines the master clock. The IEEE-1588 indicator on the front panel of the Series 3700 updates to display the IEEE-1588 status. If the indicator is off, then IEEE-1588 is disabled or the device is not connected to a working network. If the network is not working, then the LAN indicator also blinks.
Series 3700 System Switch/Multimeter Reference Manual Section 11: LXI Class B Triggering (IEEE-1588) Scheduling alarms You can schedule alarms to request the Series 3700 to perform actions at a specific time and date or at a specific time interval. You can schedule alarms in UTC or PTP time; however, it is important to be consistent in defining the alarms using the same time format whether UTC or PTP.
Section 11: LXI Class B Triggering (IEEE-1588) Series 3700 System Switch/Multimeter Reference Manual You can also schedule alarms to occur at a fractional second using either PTP or UTC format with schedule.alarm[x].fractionalseconds (on page 13250). After defining the alarm, configure the number of times you would like to repeat this alarm using schedule.alarm[x].repetition (on page 13-251). Use schedule.alarm[x].
Series 3700 System Switch/Multimeter Reference Manual Section 11: LXI Class B Triggering (IEEE-1588) LXI event log The LXI event log of a Series 3700 monitors all LAN triggers that the instrument receives or generates. The LXI event log has nine comma-delimited fields. Below is an example entry to a LXI event log and a description of the log fields in order of appearance.

Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Negative and positive transition registers Negative-transition register (NTR): When a bit in an NTR is set by the user, the corresponding bit in the event register will set when the corresponding bit in the condition register transitions from 1 to 0.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model System summary and status byte The system summary bit (SSB) is received by the status byte (Bit 1) from the system summary register (status.system) byte. The summary of system summary register (status.system) receives its extension bit (Bit 0) from the system summary register 2 (status.system2). Figure 12-2: Status byte and system summary register 3700S-901-01 Rev.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual System summary registers The system summary registers (system5 through system2) provide summary information through the specific register's extension bit (Bit 0). This in turn is provided to the system summary register (system) extension bit (Bit 0). Figure 12-3: System summary registers 12-4 3700S-901-01 Rev.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Standard event status register and enable The summary bit of the standard event status register and event status enable provide summary information to Bit 5 of the status byte (Status byte and SRQ (on page 12-2)). Figure 12-4: Standard event registers and event status enable 3700S-901-01 Rev.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Operation events registers The summary bit of the operation status user register provides the user bit (USER) (Bit 12) to the operation status register. The summary bit of the operation status register provides the operation summary bit (OSB) (Bit 7) of the status byte. Figure 12-5: Operation event registers 12-6 3700S-901-01 Rev.

Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Programming enable and transition registers The only registers that can be programmed by the user are the enable and transition registers. All other registers in the status structure are read-only registers.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Reading registers Any register in the status structure can be read by either sending the common command query (where applicable), or by including the script command for that register in either the print() or print(tostring()) command. The print() command returns a numeric value, while the print(tostring()) command returns the string equivalent.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Status byte and service request (SRQ) Service request is controlled by two 8-bit registers; the status byte register, and the service request enable register. Figure 12-9: Status byte and service request (SRQ) 12-12 3700S-901-01 Rev.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Status byte register The summary messages from the status registers and queues are used to set or clear the appropriate bits (B0, B1, B2, B3, B4, B5, and B7) of the status byte register. These summary bits do not latch, and their states (0 or 1) are solely dependent on the summary messages (0 or 1). For example, if the standard event register is read, its register will clear.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Serial polling and SRQ Any enabled event summary bit that goes from 0 to 1 sets bit B6 and generates an SRQ (service request). In your test program, you can periodically read the status byte to check if an SRQ has occurred and what caused it. If an SRQ occurs, the program can, for example, branch to an appropriate subroutine that will service the request. SRQs can be managed by the serial poll sequence of the Series 3700.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Status byte and service request commands The commands to program and read the status byte register and service request enable register are listed below. Note that the table includes both common commands and their script command equivalents. For details on programming and reading registers, see Programming enable and transition registers (on page 12-10) and Reading registers (on page 12-11).
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Controlling node and SRQ enable registers For the attributes to control system node and SRQ enable bits and read associated registers, refer to: status.request_enable (on page 13-276) status.request_event (on page 13-278) status.node_enable (on page 13-267) status.

Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Operation event registers The Series 3700 has two register sets associated with operation event status. Commands are summarized in the following table. For example, either of the following commands will set the CAL enable bit: status.operation.enable = status.operation.CAL status.operation.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Commands Bit status.operation.user.* = status.operation.user.BIT1 B1 status.operation.user.* = status.operation.user.BIT2 B2 status.operation.user.* = status.operation.user.BIT3 B3 status.operation.user.* = status.operation.user.BIT4 B4 status.operation.user.* = status.operation.user.BIT5 B5 status.operation.user.* = status.operation.user.BIT6 B6 status.operation.user.* = status.operation.user.BIT7 B7 status.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Questionable event registers The Series 3700 has five registers associated with questionable event status. For example, to set the CAL enable bit, use either of the following commands: status.questionable.enable = status.questionable.CAL status.questionable.enable = 256 The following command will request the questionable enable register value: print(status.questionable.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Commands Bit To read registers: print(status.questionable.user.*) Where * = .ntr, .ptr, .enable, .event, and .condition NOTE The first three (.ntr, .ptr, and .enable) are read/write, while the last two (.event and .condition) are read only. print(status.questionable.user.condition) print(status.questionable.user.event) Measurement event registers The Series 3700 has five registers associated with measurement event status.
Series 3700 System Switch/Multimeter Reference Manual Section 12: Status Model Commands Bit To read registers: print(status.measurement.*) Where * = .ntr, .ptr, .enable, .event, and .condition NOTE The first three (.ntr, .ptr, and .enable) are read/write, while the last two (.event and .condition) are read only. print(status.measurement.condition) print(status.measurement.
Section 12: Status Model Series 3700 System Switch/Multimeter Reference Manual Error queue The error queue holds error and status messages. When an error or status event occurs, a message that defines the error or status is placed in the error queue and the error available (EAV) bit in the status byte register is set. An error or status message is cleared from the error queue when it is read. The error queue is considered cleared when it is empty.
Section 13 Instrument Control Library (ICL) In this section: Command programming notes ........................................ 13-1 ICL command list .......................................................... 13-11 Command programming notes Wild characters For the following command reference, it is necessary to understand the following conventions. Many commands are expressed in a generic form using wild characters. A wild character indicates a channel, function, or trigger line.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual [N] The N character, enclosed by brackets ([ ]), is used in functions and attributes for the digital I/O line (1 to 14). For example, the function to assert an output trigger is generically expressed as follows: digio.trigger[N].assert To program the Series 3700 to assert an output trigger on trigger line 5, the following command statement is sent to the instrument: digio.trigger[5].
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) The results of a function call are used by assigning the return values to variables and accessing those variables. The following code will measure voltage and return the reading: dmm.func = 'dcvolts' reading = dmm.measure() print(reading) Output: 2.360000e+00 The above output indicates that the voltage reading is 2.36V. Attributes An attribute is a characteristic of an instrument feature or operation.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual Reading an attribute Reading an attribute is accomplished by passing it to a function call as a parameter or by assigning it to another variable. Parameter passing example: The following command reads the filter type for the DMM by passing the attribute to the print function, which outputs a value: print(dmm.filter.type) Output: 0.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) TSP-LinkTM nodes Each instrument or enclosure attached to the TSP-Link bus must be uniquely identified. This identification is called a TSP-Link node number, and the enclosures are called nodes. Each node must be assigned a unique node number. In relation to Test Script Processor (TSPTM), nodes look like tables.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual Logical instruments also look like TSP tables. In addition to the logical instrument-specific attributes and the commands to which they respond, there are a few attributes that provide information about the logical instrument. These attributes are listed below: name: A string that represents the logical instrument's name. For example, dmm.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) If the command was channel.getstate instead of channel.getcount, then 72 zero (0) or one (1) values would be returned (a 0 would indicate that the channel or backplane is open; a 1 would indicate that it is closed). The first 60 values are for Channels 1 to 60 (starting at 1 and increasing to 60). The last 12 values are the backplane relays (starting with Bank 1, Relay 1, increasing to Bank 2, Relay 6).
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual DMM configuration When a DMM configuration is updated, the instrument will go through all switch channels in the system to find ones that have the updated configuration assigned as its DMM configuration attribute setting. For each one found, it will verify that the new configuration attribute settings are still valid for that channel.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) The output will be 60 comma-delimited myconfig strings, as follows: myconfig,myconfig,myconfig,myconfig,myconfig,myconfig,mycon fig,myconfig,myconfig,myconfig,myconfig,myconfig,myconfi g,myconfig,myconfig,myconfig,myconfig,myconfig,myconfig, myconfig,myconfig,myconfig,myconfig,myconfig,myconfig,my config,myconfig,myconfig,myconfig,myconfig,myconfig,myco nfig,myconfig,myconfig,myconfig,myconfig,myconfig,mycon
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual If you now associate 'myconfig' with a 2-wire temperature function, 'myconfig' stays on Channels 1 to 30, but because Channels 31 to 60 are no longer paired, they are set back to a default DMM configuration setting of 'nofunction' because the unit has no way of knowing what configuration is desired on those channels.

Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual Using channel.*() ICL commands Unless otherwise noted, channel.*() Instrument Control Library (ICL) commands use the channel list and return the value syntax described below. The channel list is specified according to the syntax presented in the channel list legend. Not all ICL commands support the fully described syntax. Any exclusions are noted in a specific command's documentation.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) Error Message Description invalid label or pattern name A string was found in the channel list that does not specify any known label or pattern name. no patterns accepted A pattern was specified for an ICL command that does not support patterns as input. no multiple channels accepted Multiple channels were specified for an ICL command that acts only on a single channel.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual Return value The return value is a string containing a list of comma-delimited individual return items. The channel list argument of the ICL command determines the number and order of these returned items. When the channel list parameter for this function is 'slotX', the response first lists the channels starting from lowest to highest.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) channel.calibration.adjustcount() Example To query for the adjustment count: CalCount = channel.calibration.adjustcount("1010") channel.calibration.adjustdate() Function Sets or gets the adjustment date in UTC format (number of seconds since January 1, 1970) on the unlocked channel. Usage mydate = channel.calibration.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual channel.calibration.lock() Remarks This command locks calibration on the card being calibrated, but does not save calibration data (which is lost if it is not saved before locking). Once locked, you must unlock calibration to perform it again. Only one card can be calibrated at a time. Therefore, the lock function works only on the currently unlocked card.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) channel.calibration.save() Remarks Only one card can be calibrated at a time. Therefore, the save function works only on the currently unlocked card. An error is generated if this command is issued when calibration is already locked. The system must receive this command before the channel.calibration.lock() (on page 13-31) command or the data will be lost.
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual channel.calibration.step() Remarks The specified channel must be on the unlocked slot. Only DAC and totalizer channels can be calibrated. It is best to calibrate a single channel sequentially to completion before changing channels. The card assumes that the given voltage or current value is exactly what it is sourcing for the given step.
Series 3700 System Switch/Multimeter Reference Manual Section 13: Instrument Control Library (ICL) channel.calibration.unlock() Remarks There is only one password per card. Therefore, the only acceptable values for channel list are slot1, slot2, and so on. Otherwise, an error is generated. An error is generated if the password that is entered does not match the one that was saved with channel.calibration.password() (on page 13-32).
Section 13: Instrument Control Library (ICL) Series 3700 System Switch/Multimeter Reference Manual channel.calibration.verifydate() Example To query the number of seconds since January 1, 1970: CalDate = channel.calibration.verifydate() To set the calibration verification date on Slot 1 based on the current date of the system: channel.calibration.verifydate(os.time()) To set the calibration verification date on Slot 1 as July 4, 2006: channel.calibration.verifydate(os.
