Syntax and Commands
Command Syntax Command Syntax You can control the oscilloscope through the GPIB, RS-232, or USB interface using a large group of commands and queries. This section describes the syntax these commands and queries use and the conventions the oscilloscope uses to process them. The commands and queries themselves are listed in the Command Descriptions section.
Command Syntax Command and Query Structure Commands consist of set commands and query commands (usually simply called commands and queries). Commands change oscilloscope settings or perform a specific action. Queries cause the oscilloscope to return data and information about its status. Most commands have both a set form and a query form. The query form of the command is the same as the set form except that it ends with a question mark.
Command Syntax Figure 2-1: Command message elements Commands Commands cause the oscilloscope to perform a specific function or change one of its settings. Commands have the structure: [:][[]...] A command header is made up of one or more mnemonics arranged in a hierarchical or tree structure. The first mnemonic is the base or root of the tree and each subsequent mnemonic is a level or branch off of the previous one.
Command Syntax Clearing the Output Queue To clear the output queue and reset the oscilloscope to accept a new command or query, send a Device Clear (DCL) from a GPIB host. From an RS-232 host, send a break signal. The RS-232 interface responds by returning the ASCII string "DCL." From a USB host, send an INITIATE_CLEAR followed by a CHECK_CLEAR_STATUS. The USB interface responds to CHECK_CLEAR_STATUS with STATUS_SUCCESS when it is finished clearing the output queue.
Command Syntax ACQuire:MODe AVErage; NUMAVg 16 The longer version works equally well: ACQuire:MODe AVErage;:ACQuire:NUMAVg 16 Never precede a star (*) command with a colon or semicolon: ACQuire:MODe AVErage;*TRG The oscilloscope processes commands that follow the star command as if the star command was not there, so: ACQuire:MODe AVErage;*TRG;NUMAVg 16 sets the acquisition mode to average and sets acquisition averaging to 16. The *TRG command is ignored.
Command Syntax GPIB End of Message (EOM) Terminators. GPIB EOM terminators can be the END message (EOI asserted concurrently with the last data byte), the ASCII code for line feed (LF) sent as the last data byte, or both. The oscilloscope always terminates messages with LF and EOI. White space is allowed before the terminator; for example, CR LF is acceptable. USB End of Message (EOM) Terminators.
Command Syntax Waveform Mnemonics Cursor Position Mnemonic Measurement Specifier Mnemonics In some commands you can specify a waveform without regard to its type: channel waveform, math waveform, or reference waveform. The "y" is the same as "x" in Reference Waveform Mnemonics. Symbol Meaning Can be CH, MATH, or REF When the oscilloscope displays cursors, commands may specify which cursor of the pair to use. Symbol Meaning POSITION A cursor selector; is 1 or 2.
Command Syntax Table 2-6: Oscilloscope handling of incorrect numeric arguments Quoted String Arguments Argument value Oscilloscope response Numeric argument is less than lowest correct value for that command Sets the specified command to the lowest correct value and executes the command Numeric argument is greater than the highest correct value for that command Sets the specified command to the highest correct value and executes the command Numeric value is between two correct values Rounds the en
Command Syntax Block Arguments Several oscilloscope commands use a block argument form. Table 2-7: Parts of a block argument Symbol Meaning A nonzero digit character, in the range 1-9 Specifies the number of elements that follow A digit character, in the range 0-9 A character with the hex equivalent of 00 through FF hexadecimal (0 through 255 decimal) A block of data bytes, defined as: := { #[...][...] | #0[...

Status and Events
Status and Events The oscilloscope provides a status and event reporting system for the GPIB, RS-232, and USB interfaces. This system informs you of certain significant events that occur within the oscilloscope. The oscilloscope status reporting system consists of five 8-bit registers and two queues. This section describes these registers and components, and explains how the event handling system operates.
Status and Events Table 3-1: SESR bit functions (cont.) Bit Function 6 URQ User Request. Indicates that an application event has occurred. *See note. 5 CME 4 EXE Command Error. Shows that an error occurred while the oscilloscope was parsing a command or query. Execution Error. Shows that an error executing a command or query. 3 DDE Device Error. Shows that a device error occurred. 2 QYE Query Error.
Status and Events Table 3-2: SBR bit functions (cont.) Bit Function 4 MAV Message Available. Shows that output is available in the Output Queue. 2 ———— Not used. ———— Not used. 1–0 ———— Not used. 3 Enable Registers DESER, ESER, and SRER allow you to select which events are reported to the Status Registers and the Event Queue.
Status and Events Use the *SRE command to set the SRER. Use the *SRE? query to read the register. The RQS bit remains set to one until either the Status Byte Register is read with a Serial Poll or the MSS bit changes back to a zero. Figure 3-5: The Service Request Enable Register (SRER) *PSC Command The *PSC command controls the Enable Registers contents at power-on.
Status and Events Event Queue The Event Queue stores detailed information on up to 20 events. If than 20 events stack up in the Event Queue, the 20th event is replaced by event code 350, "Queue Overflow." Read the Event Queue with the EVENT? query (which returns only the event number), with the EVMSG? query (which returns the event number and a text description of the event), or with the ALLEV? query (which returns all the event numbers with a description of the event).
Status and Events Figure 3-6: Status and Event Handling Process When an event occurs, a signal is sent to the DESER (1). If that type of event is enabled in the DESER (that is, if the bit for that event type is set to 1), the appropriate bit in the SESR is set to one, and the event is recorded in the Event Queue (2). If the corresponding bit in the ESER is also enabled (3), then the ESB bit in the SBR is set to one (4). When output is sent to the Output Queue, the MAV bit in the SBR is set to one (5).
Status and Events Synchronization Methods Overview Although most commands are completed almost immediately after being received by the oscilloscope, some commands start a process that requires time. For example, once a single sequence acquisition command is executed, depending upon the applied signals and trigger settings, it may take an extended period of time before the acquisition is complete.
Status and Events /** Set up conditional acquisition **/ ACQUIRE:STATE OFF SELECT:CH1 ON HORIZONTAL:RECORDLENGTH 1000 ACQUIRE:MODE SAMPLE ACQUIRE:STOPAFTER SEQUENCE /** Acquire waveform data **/ ACQUIRE:STATE ON /** Set up the measurement parameters **/ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT: IMMED:SOURCE CH 1 /** Take amplitude measurement **/ MEASUREMENT: MEAS1:VALUE? The acquisition of the waveform requires extended processing time.
Status and Events /* Set up conditional acquisition */ ACQUIRE:STATE OFF SELECT:CH1 ON ACQUIRE:MODE SAMPLE ACQUIRE:STOPAFTER SEQUENCE /* Acquire waveform data */ ACQUIRE:STATE ON /* Set up the measurement parameters */ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT:IMMED:SOURCE CH1 /* Wait until the acquisition is complete before taking the measurement*/ */ *WAI /* Take amplitude measurement */ MEASUREMENT:IMMED:VALUE? The controller can continue to write commands to the input buffer of the oscilloscope, bu
Status and Events many commands to the input buffer. The controller is still tied up though, and the repeated BUSY? query will result in bus traffic. Using the *OPC Command If the corresponding status registers are enabled, the *OPC command sets the OPC bit in the Standard Event Status Register (SESR) when an operation is complete. You achieve synchronization by using this command with either a serial poll or service request handler.
Status and Events The same command sequence using the *OPC command for synchronization looks like this /* Set up conditional acquisition */ ACQUIRE:STATE OFF SELECT:CH1 ON ACQUIRE:MODE SAMPLE ACQUIRE:STOPAFTER SEQUENCE /* Enable the status registers */ DESE 1 *ESE 1 *SRE 32 /* Acquire waveform data */ ACQUIRE:STATE ON /* Set up the measurement parameters */ MEASUREMENT:IMMED:TYPE AMPLITUDE MEASUREMENT:IMMED:SOURCE CH1 /* Wait until the acquisition is complete before taking the measurement*/ *OPC The progr
Status and Events /* Take amplitude measurement */ MEASUREMENT:IMMED:VALUE? This is the simplest approach. It requires no status handling or loops. However, you must set the controller time-out for longer than the acquisition operation. Messages The information contained in the topic tabs above covers all the programming interface messages the oscilloscope generates in response to commands and queries.

Programming Examples
Programming Examples The following series of commands and queries illustrate many of the most common commands and techniques. To use these commands and queries over USB, you must use a program or routines that interface to the USBTMC driver on your PC. You can also use the PC Communications software that came on the CD with your oscilloscope to get the same data without having to write programs. For operating information, you can launch the PC Communications software and refer to the online help.

Glossary
Glossary ASCII Acronym for the American Standard Code for Information Interchange. Controllers transmit commands to the digitizing oscilloscope using ASCII character encoding. Address A 7-bit code that identifies an instrument on the communication bus. The digitizing oscilloscope must have a unique address for the controller to recognize and transmit commands to it. Backus-Naur Form (BNF) A standard notation system for command syntax. The syntax in this manual use BNF notation.
Glossary unasserts the SRQ line (GPIB only). Devices not requiring service return a status byte with bit 6 cleared. USB An acronym for Universal Serial Bus. USBTMC An acronym for USB Test and Measurement Class. USB488 The USBTMC subclass specification that implements an IEEE488-like interface over USB.
