HP E1432A User's Guide Using the HP E1432A Introduction This chapter shows how to use the HP E1432A using the VXIplug&play Host Interface Library. The Host Interface Library for the HP E1432A is a set of functions that allow the user to program the register-based HP E1432A at a higher level than register reads and writes. The library allows groups of HP E1432As to be set up and programmed as if they were one entity Two versions of the Host Interface Library are included.
HP E1432A User's Guide Using the HP E1432A What is VXIplug&play? Hewlett-Packard uses VXIplug&play technology in the HP E1432A. This section outlines some of the details of VXIplug&play technology. Overview The fundamental idea behind VXIplug&play is to provide VXI users with a level of standardization across different vendors well beyond what the VXI standard specifications spell out. The VXIplug&play Alliance specifies a set of core technologies centering on a standard instrument driver technology.
HP E1432A User's Guide Using the HP E1432A The actual instrument driver itself is a DLL (Dynamic Linked Library) created from: q A set of source (.C) files. q A set of header (.H) files, used for compiling the file as well as to describe the driver’s calls to any program using the driver. q A standard driver library (.LIB) file, to provide the standard functionality all the drivers would require.
HP E1432A User's Guide Using the HP E1432A The Soft Front Panel (SFP) The Soft Front Panel is a stand-alone Windows application, built on top of the VXIplug&play driver DLL; it is used for instrument evaluation and debugging and as a demo. It is not a programmable interface to the instrument, nor can it be used to generate code. The soft front panel also accesses the same Windows Help file as provided with the DLL.

HP E1432A User's Guide Using the HP E1432A Channels and groups This section gives some information about using channels and groups. For more detailed information see the HP E1432A help text. Channel Groups In the HP E1432A VXIplug&play driver, a channel group is the basic unit of hardware control. Any channel you want to control must first be assigned to a group with the hpe1432_createChannelGroup function.
HP E1432A User's Guide Using the HP E1432A Creating a Channel Group The function hpe1432_createChannelGroup creates and initializes a channel group. A channel group allows you to issue commands to several HP E1432A channels at once, simplifying system setup. You can overlap channel groups. The state of an individual HP E1432A channel that is in more than one channel group is determined by the most recent operation performed on any group to which this channel belongs.
HP E1432A User's Guide Using the HP E1432A Multiple-module/mainframe Measurements Grouping of Channels/Modules The interface library for the HP E1432A is designed to allow programming of several channels from one or several distinct modules, as if they were one entity. Each HP E1432A module has up to 16 channels. The library may control up to a maximum of 255 HP E1432A modules (8160 channels).
HP E1432A User's Guide Using the HP E1432A All modules except the “system module” need to be set to use the VXI TTL trigger lines as the clock source. Use hpe1432_setClockSource for this. Set the “system module” to output the clock. Use hpe1432_setClockMaster for this. After this is done, all system sync pulses come from the “system module” and drive the measurement state machines on all boards in the group.
HP E1432A User's Guide Using the HP E1432A Managing Multiple-mainframe Measurements In a single-mainframe measurement, the HP E1432A communicates with other HP E1432As through the TTLTRG lines. However, when using the VXI-MXI bus extender modules, the TTLTRG lines, which carry the group synchronization pulse and sample clock, are extended only in one direction. This unidirectional signal connection restricts the types of measurements you can make in a multiple mainframe environment.
HP E1432A User's Guide Using the HP E1432A In the example above, Mainframe A contains the Slot 0 Controller for a multiple mainframe system. Mainframe A is connected to Mainframe B with a VXI-MXI interface, HP E1482B. To successfully manage this multiple mainframe environment, use the following guidelines. q q q q q q q q q Locate modules with logical addresses less than 128 in Mainframe A.

HP E1432A User's Guide Using the HP E1432A Synchronization in Multiple-mainframe Measurements A TTL Trigger line between HP E1432As making group measurements keeps all modules synchronized. This is an open-collector line where each module holds the one designated as the SYNC line low until the module is ready to advance to the next measurement state. Another TTL Trigger line is designated to carry the sample clock to all modules.
HP E1432A User's Guide Using the HP E1432A Module Features Data Flow Diagram and FIFO Architecture The illustration on the next page shows data flow in the HP E1432A. In this example there are four 4-channel input assemblies for a total of 16 input channels. The data for all channels is sent to the FIFO. The FIFO is divided into sections, one for each channel. The data moves through a circular buffer (first-in-first-out) until a trigger causes it to be sent on to the VME Bus.

HP E1432A User's Guide Using the HP E1432A Additional Notes on Measurement Spans Bottom reference is 10 Hz, max span is 20 kHz. Top span 23000 Hz = 460 lines. To select a sample frequency for time domain data, first divide the desired sample frequency by 2.56 to convert it to a measurement span. Then locate the closest measurement span on this table and choose the corresponding sample frequency at top of the table.
HP E1432A User's Guide Using the HP E1432A Measurement Process Measurement Setup and Control When the HP E1432A makes a measurement, the measurement itself consists of two phases: the measurement initialization, and the measurement loop. Each of these phases consists of several states, through which the measurement progresses. The transition from one state to the next is tied to a transition in the Sync/Trigger line (one of the TTL trigger lines on the VXI back plane).
HP E1432A User's Guide Using the HP E1432A Parameter Settings Many parameters are channel-dependent, meaning that each channel can be set independently of the others in the module. Other parameters are module-dependent; changing a module-dependent parameter for a channel will change it for all channels on that module. For example, changing blocksize, a module-dependent parameter, for input channel 3 will also change the block size for all other channels in the same HP E1432A module as channel 3.
HP E1432A User's Guide Using the HP E1432A In the BOOTING state, the digital processors of the module load their parameters, and their program. Once done, the module releases the Sync/Trigger line and moves to the BOOTED state. The HP E1432A stays in the BOOTED state until it sees a high-to-low transition of the Sync/Trigger line (that is, all the HP E1432As in the system have booted).
HP E1432A User's Guide Using the HP E1432A Upon entering the ARM state the HP E1432A starts saving new data in its FIFO. It remains in the ARM state until the Sync/Trigger line goes high. If the HP E1432A is programmed with a pre-trigger delay, it collects enough data samples to satisfy this pre-trigger delay, and then releases the Sync/Trigger line. If no pre-trigger delay has been programmed, it releases the Sync/Trigger line immediately.
HP E1432A User's Guide Using the HP E1432A Arm and Trigger This section explains some terminology relating the the “Arm” and “Trigger” steps in the measurement loop. As an example a measurement might be set up to arm at a certain RPM level and then subsequently trigger at an external event corresponding to top dead center (TDC).
HP E1432A User's Guide Using the HP E1432A HP E1432A Triggering. The following is a short discussion of triggering for the HP E1432A. Triggering is defined as the transition from the armed state to the triggered state. This transition is caused by a low going edge on a TTL trigger line. The function hpe1432_getTtltrgLines selects which of the eight TTL trigger lines is to be used.
HP E1432A User's Guide Using the HP E1432A Trigger Level To set the trigger level, use hpe1432_setTriggerMode to select “level” or “bound” mode; and use hpe1432_setTriggerLevel twice to set both the upper and lower trigger levels. The difference between the upper and lower trigger levels must be at least 10% of full scale (and 10% is usually the best amount). Also use hpe1432setTriggerSlope to specify a positive or negative trigger slope.
HP E1432A User's Guide Using the HP E1432A Data Transfer Modes The HP E1432A can be programmed to use either of two data transfer modes: overlap block mode and continuous mode. To help explain these modes we will first describe block mode. Block Mode (HP E1431A) The HP E1432A’s overlap block mode is similar the block mode which is used in other Hewlett-Packard instruments such as the HP E1431A. In block mode, the input hardware acquires one block after getting an arm and trigger.
HP E1432A User's Guide Using the HP E1432A Limit on Queuing of Data In overlap block mode, a number of trigger events may be queued up before the host reads the data for those triggers. The host may get further and further behind the data acquisition. However, if the host gets far enough behind that the FIFO fills up, data acquisition must momentarily stop and wait for data to get transferred to the host. This places a limit on how far in time the host can be behind the data acquisition.
HP E1432A User's Guide Using the HP E1432A HP E1432A Interrupt Behavior Interrupt Setup For an example of interrupt handling see the program event.c in the examples directory. The HP E1432A VXI module can be programmed to interrupt a host computer using the VME interrupt lines. VME provides seven such lines. Using hpe1432_setInterruptPriority, you can set up the HP E1432A module to use any one of them. The HP 1432A can interrupt the host computer in response to different events.
HP E1432A User's Guide Using the HP E1432A Once it has done this interrupt, the module will not do any more VME interrupts until re-enabled with hpe1432_reenableInterrupt. Normally, the last thing a host computer’s interrupt handler should do is call hpe1432_reenableInterrupt. Events that would have caused an interrupt, but which are blocked because hpe1432_reenableInterrupt has not yet been called, will be saved.
HP E1432A User's Guide Using the HP E1432A q Calling hpe1432_createChannelGroup to delete a group that is simultaneously being used by non-interrupt-handler code. q Calling one of the read data functions (hpe1432_readRawData or hpe1432_readFloat64Data), if the non-interrupt-handler code is also calling one of these functions. q Calling hpe1432_init to reset the list of channels that are available to the HP E1432A library.
HP E1432A User's Guide Using the HP E1432A After firmware is installed, and after a call to hpe1432_preset, all of the parameters (both channel-specific and global) in an HP E1432A module are set to their default values. For channel-specific parameters, the default value may depend on the type of channel. Some channel-specific parameters apply only to a specific type of channel. For example, tach holdoff applies only to tach channels.
HP E1432A User's Guide Using the HP E1432A New features of the HP E1432A/HP E1433A software The following features have been added to the HP E1432A/HP E1433A software since the previous edition of this manual. These and other features are documented in the online Function Reference. For more information look in the Function Reference entries for the functions that are used by the feature. Auto range Auto range calculates the best range for each channel so that the signal is full scale but not overloaded.
HP E1432A User's Guide Using the HP E1432A Zoom (HP E1432A only) Up to now the HP E1432A has made only baseband measurements (from zero to some frequency.) Zoom allows you to set a center frequency and look at a window of frequencies around it. It uses two new functions: hpe1432_setZoom (turns zoom on/off) and hpe1432_setCenterFreq. (Zoom has not been implemented for the HP E1433A). Zoom (for the Arbitrary Source, option 1D4) This is similar to zoom for the HP E1432A input.

4 The C-Language Host Interface Library 4-1
HP E1432A User's Guide The C-Language Host Interface Library Introduction The Host Interface Library for the HP E1432A is a set of functions that allow you to program the register-based HP E1432A at a higher level than register reads and writes. The library allows groups of HP E1432As to be set up and programmed as if they were one entity. Two version of the Host Interface Library are available.
HP E1432A User's Guide The C-Language Host Interface Library Header and Library Files The /opt/e1432/lib directory contains several versions of the HP E1432A Host Interface library: lib1432.a A normal HP-UX archive library, used by host programs wanting to talk to HP E1432A hardware. lib1432.sl An HP-UX shared library, used by host programs wanting to talk to HP E1432A hardware. This and the above archive library do exactly the same things.
HP E1432A User's Guide The C-Language Host Interface Library Parameter Information Description of HP E1432A Parameters Some parameters, such as range or coupling, apply to specific channels. When a channel ID is given to a function that sets a channel-specific parameter, only that channel is set to the new value. Some parameters, such as clock frequency or data transfer mode, apply globally to a module.
HP E1432A User's Guide The C-Language Host Interface Library Parameter Lists This section shows which parameters are global parameters, which are channel-specific, and what types of channels the channel-specific parameters apply to. Default values are shown for all of these parameters. In addition, each parameter is categorized as “abort”, “wait”, “immediate”, or “glitch” depending on the behavior when this parameter is changed during a running measurement. Those with “abort” cause the measurement to abort.

HP E1432A User's Guide The C-Language Host Interface Library Channel and Group IDs Most functions in the HP E1432A C-Language Host Interface Library take an ID parameter which specifies what channel or group of channels the function should apply to. The ID can either be a channel ID or a group ID. If a group ID is used, then the function is applied to each channel contained in the group. Channel IDs Channel IDs are logical IDs which are created by a call to e1432_assign_channel_numbers.
HP E1432A User's Guide The C-Language Host Interface Library For example, to set the range of the third input channel to 10 volts, the source code would look something like: status = e1432_set_range(hwid, E1432_INPUT_CHAN(3), 10.0); Group IDs Group IDs are logical IDs which are created by a call to e1432_create_channel_group. This function can be called multiple times to create multiple groups, and each group can contain any combination of channels, including mixtures of different types of channels.
HP E1432A User's Guide The C-Language Host Interface Library Multiple-module/Mainframe Measurements Grouping of Channels/Modules The interface library for the HP E1432A is designed to allow programming of several channels from one or several distinct modules, as if they were one entity. Each HP E1432A module has up to 16 channels. The library may control up to a maximum of 255 HP E1432A modules (8160 channels).
HP E1432A User's Guide The C-Language Host Interface Library One module of the set of modules needs to be set to output the sync pulse. Tthe module with the lowest VXI logical address is called the “system module” and assigned this duty. This can be set with the e1432_set_multi_sync function call, using the lowest channel ID in the group (NOT the group ID). All modules except the “system module” need to be set to use the VXI TTL trigger lines as the clock source. Use e1432_set_clock_source for this.
HP E1432A User's Guide The C-Language Host Interface Library Managing Multiple-mainframe Measurements In a single mainframe measurement, the HP E1432A communicates with other HP E1432As through the TTLTRG lines. However, when using the VXI-MXI bus extender modules, the TTLTRG lines, which carry the group synchronization pulse and sample clock, are extended only in one direction. This unidirectional signal connection restricts the types of measurements you can make in a multiple mainframe environment.
HP E1432A User's Guide The C-Language Host Interface Library In the example above, Mainframe A contains the Slot 0 Controller for a multiple mainframe system. Mainframe A is connected to Mainframe B with a VXI-MXI interface, HP E1482B. To successfully manage this multiple mainframe environment, use the following guidelines. q q q q q q q q q Locate modules with logical addresses less than 128 in Mainframe A. Locate modules with logical addresses greater than 127 in Mainframe B.

HP E1432A User's Guide The C-Language Host Interface Library Synchronization in Multiple-mainframe Measurements A TTL Trigger line between HP E1432As making group measurements keeps all modules synchronized. This is an open-collector line where each module holds the one designated as the SYNC line low until the module is ready to advance to the next measurement state. Another TTL Trigger line is designated to carry the sample clock to all modules.
HP E1432A User's Guide The C-Language Host Interface Library Measurement Process Measurement Setup and Control When the HP E1432A makes a measurement, the measurement itself consists of two phases: the measurement initialization, and the measurement loop. Each of these phases consists of several states, through which the measurement progresses. The transition from one state to the next is tied to a transition in the Sync/Trigger line (one of the TTL trigger lines on the VXI back plane).
HP E1432A User's Guide The C-Language Host Interface Library Parameter Settings Many parameters are channel-dependent, meaning that each channel can be set independently of the others in the module. Other parameters are module-dependent; changing a module-dependent parameter for a channel will change it for all channels on that module.
HP E1432A User's Guide The C-Language Host Interface Library In the BOOTING state, the digital processors of the module load their parameters, and their program. Once done, the module releases the Sync/Trigger line and moves to the BOOTED state. The HP E1432A stays in the BOOTED state until it sees a high-to-low transition of the Sync/Trigger line (that is, all the HP E1432As in the system have booted).
HP E1432A User's Guide The C-Language Host Interface Library Upon entering the ARM state the HP E1432A starts saving new data in its FIFO. It remains in the ARM state until the Sync/Trigger line goes high. If the HP E1432A is programmed with a pre-trigger delay, it collects enough data samples to satisfy this pre-trigger delay, and then releases the Sync/Trigger line. If no pre-trigger delay has been programmed, it releases the Sync/Trigger line immediately.
HP E1432A User's Guide The C-Language Host Interface Library Arm and Trigger This section explains some terminology relating the the “Arm” and “Trigger” steps in the measurement loop. As an example a measurement might be set up to arm at a certain RPM level and then subsequently trigger at an external event corresponding to top dead center (TDC).
HP E1432A User's Guide The C-Language Host Interface Library HP E1432A Triggering. The following is a short discussion of triggering for the HP E1432A. Triggering is defined as the transition from the armed state to the triggered state. This transition is caused by a low going edge on a TTL trigger line. Which one of the eight TTL trigger line is chosen by e1432_get_ttltrg_lines().
HP E1432A User's Guide The C-Language Host Interface Library Data Transfer Modes The HP E1432A can be programmed to use either of two data transfer modes: overlap block mode and continuous mode. To help explain these modes we will first describe block mode. Block Mode (HP E1431A) The HP E1432A’s overlap block mode is similar the block mode which is used in other Hewlett-Packard instruments such as the HP E1431A. In block mode, the input hardware acquires one block after getting an arm and trigger.
HP E1432A User's Guide The C-Language Host Interface Library Limit on Queuing of Data In overlap block mode, a number of trigger events may be queued up before the host reads the data for those triggers. The host may get further and further behind the data acquisition. However, if the host gets far enough behind that the FIFO fills up, data acquisition must momentarily stop and wait for data to get transferred to the host. This places a limit on how far in time the host can be behind the data acquisition.
HP E1432A User's Guide The C-Language Host Interface Library HP E1432A Interrupt Behavior Interrupt Setup The HP E1432A VXI module can be programmed to interrupt a host computer using the VME interrupt lines. VME provides seven such lines, and the HP E1432A module can be told to use any one of them (see e1432_set_interrupt_priority). The HP 1432A can interrupt the host computer in response to different events. You can specify a mask of events on which to interrupt.
HP E1432A User's Guide The C-Language Host Interface Library HP E1432A Interrupt Handling To make the HP E1432A module do the interrupt, both a mask and a VME Interrupt line must be specified, by calling e1432_set_interrupt_mask and e1432_set_interrupt_priority respectively. Once the mask and line have been set, and an interrupt occurs, the cause of the interrupt can be obtained by reading the E1432_IRQ_STATUS_REG register (using e1432_read_register).
HP E1432A User's Guide The C-Language Host Interface Library Host Interrupt Handling When the HP E1432A asserts the VME interrupt line, SICL will cause the specified interrupt handler to get called. Typically the interrupt handler routine will read data from the module, and then re-enable HP E1432A interrupts with e1432_reenable_interrupt. The call to e1432_reenable_interrupt must be done unless the host is not interested in any more interrupts.
HP E1432A User's Guide The C-Language Host Interface Library HP E1432A Parameters Some parameters, such as range or coupling, apply to specific channels. When a channel ID is given to a function that sets a channel-specific parameter, only that channel is set to the new value. Some parameters, such as clock frequency or data transfer mode, apply globally to a module. When a channel ID is used to change a parameter that applies to a whole module, the channel ID is used to determine which module.

Appendix A Register Definitions A-1
HP E1432A User's Guide Register Definitions The HP E1432A VXI Registers The HP E1432A 16 Channel 51.2 kSa/s Digitizer plus DSP is a register-based VXI device. Unlike message-based devices which use higher-level programming using ASCII characters, register-based devices are programmed at a very low level using binary information. The greatest advantage of this is speed. Register-based devices communicate at the level of direct hardware manipulation and this can lead to much greater system throughput.
HP E1432A User's Guide Register Definitions Address 3E16 3C16 3A16 3816 3616 3416 3216 3016 2E16 2C16 2A16 2816 2616 2416 2216 2016 1E16 1C16 1A16 1816 1616 1416 1216 1016 0E16 0C16 0A16 0816 0616 0416 0216 0016 Read Write Parameter 7 Register Parameter 6 Register Parameter 5 Register Parameter 4 Register Parameter 3 Register Parameter 2 Register Parameter 1 Register Query Response Register Command Register FIFO Count Send Data Receive Data RAM 1 RAM 0 IRQ Status Register IRQ Reset Register IRQ Conf
HP E1432A User's Guide Register Definitions The A24 Registers The following A24 registers are accessible at the base address defined by the device’s offset Register. The registers at offsets 0 to E16 are not accessible using longword (D32) accesses. The registers at offsets 1016 to FFFFF16 may be accessed by any of the of the D08(EO), D16, or D32 modes.
HP E1432A User's Guide Register Definitions The VXI Bus Registers are defined as follows: q Id Register: A read of this 16 bit register provides information about the device’s configuration. Its value is always CFFF16 as defined in the following table. Bit Contents 15-14 11 (Register Based Device) 13-12 00 (A16/A24) 11-0 111111111111 (HP’s ID) q Logical Address Register: A write to this register changes the device’s logical address according to the VXI Bus Dynamic Configuration protocol.
HP E1432A User's Guide Register Definitions Data Ready: A one (1) indicates that there is at least one word (32 bits) of data available in the Send Data register. A zero (0) indicates that there is not valid data in the Send Data register. ST Done: A one (1) indicates that the internal DSP has competed and passed its self test. Loaded: A one (1) indicates that the internal DSP has successfully booted and has loaded a valid model code.
HP E1432A User's Guide Register Definitions q Control Register: A write to this register causes specific actions to be executed by the device. The actions are described in the following table. Bit 15 14-2 1 0 A24/A32 Contents Unused Sysfail Inhibit Reset Enable A24/A32 Enable: A one (1) in this field enables access to the device’s A24 VME Bus registers. A zero (0) disables such access. Sysfail Inhibit: A one (1) disables the device from driving the SYSFAIL* line.
HP E1432A User's Guide Register Definitions q Page Map Register: This read/write register defines the internal location of the movable window into the device’s DSP bus. (This 512 kB window begins at 512 kB into the device’s A24 registers.) The eight least significant bits of the Page Map register are the page number.
HP E1432A User's Guide Register Definitions q IRQ Status Register: This read-only register indicates the reason for asserting the VME Bus interrupt. The format of the data is identical to that of the Status/ID word returned by an interrupt acknowledge (IACK) cycle. It differs from the IACK cycle in that the IACK cycle will clear the status bits and cause the de-assertion of the IRQ line.
HP E1432A User's Guide Register Definitions q Parameter 1-7 Registers: These are 32-bit RAM locations used to pass parameters along with commands to the device or query responses from the device. See the following section regarding D16/D08 access of 32-bit registers and the communication protocol. 32-bit Registers Several of the A16 registers (and all other 24-bit registers) are implemented as 32-bit-only resources. These are accessible using VME Bus D16 and D08(EO) accesses.
HP E1432A User's Guide Register Definitions Writing 32-bit Registers When writing to a 32-bit register using 8- or 16-bit modes, a simple caching scheme is also employed. On any write not including the least significant byte (highest address), the data is latched into the write cache. A write to the least significant byte causes the cached data to be written to the 32-bit register (in parallel with the current data for the least significant bytes(s). This mechanism has its own hazards.
HP E1432A User's Guide Register Definitions Command/Response Protocol The Command/Response protocol uses the following resources: q q q q Command/Query Response register implemented as a general purpose RAM Three parameter registers implemented as a general purpose RAM Additional A24 accessible RAM contiguous with the parameter registers The Command Ready, Query Response Ready, Err*, and Done bits of the Status register.
HP E1432A User's Guide Register Definitions In order to avoid contention and/or invalid data reads, there are certain rules that must be observed: 1 A controller must not write to any of the RAM registers when 2 3 4 5 6 7 8 9 10 Command/Parameter Ready is false. The DSP must not write to any of the RAM registers when either Command/Parameter Ready or Query Response Ready is true. A controller must not read any of the RAM registers when Query Response Ready is false.
HP E1432A User's Guide Register Definitions Wait for Done This is the procedure to wait for command completion and check for error. 1 Wait for Command/Parameter Ready true. 2 Wait for Done true. 3 If Err* = 0 , handle error. Complex Sequences A robust procedure for sending a query and reading the response would look like this: 1 Send Command. 2 Wait for Done. 3 If no error then Read Response. Multiple commands may be sent with a test for errors at the end of the sequence.
HP E1432A User's Guide Register Definitions DSP Bus Registers There are two 32-bit registers in the DSP bus address space. The VXI FPGA does not assert TA* when these registers are accessed. 200A16 DSP Command Register 200B16 Boot Register Note that these registers appear multiple times in the memory map, since only the address lines A31-30, A17-13, A9-8, and A3-0 are used for decoding.
HP E1432A User's Guide Register Definitions q DSP Command Register: This register is used to assert VXI interrupts and toggle various status register bits. Many of the bits in this register are grouped into related Clock and Value pairs. This allow the bits to be modified independently with single register writes. In order to change an output value, the Clock bit must be written as a one (1), while the Value is written as the desired output value.
