This chapter describes how to set up an HP-IB remote control system, and the basic use of HP-IB commands.

Remote Control, Overview

HP-IB Remote Control System, Overview

This section describes the configuration of an HP-IB remote control system.

System configuration

Connect HP 4294A and an external controller (computer) by use of an HP-IB cable. Figur e 2-1 shows an overview of the configuration of an HP-IB remote control system.

Figure 2-1 Configuration of an HP-IP remote control system

What is HP-IB?

HP-IB (Hewlett-Packard Interface Bus) is one of interface standards for connecting a computer and peripheral devices, and complies with IEEE 488.1, IEC-625, IEEE 48 8.2 and JIS-C1901, which are worldwide standards. Using the HP-IB interface allows you to control HP 4294A from an external computer. The computer sends commands and instructions through the HP-IB to HP 4294A and receives data sent from HP 4294A.

26 Chapter 2

Remote Control, Overview

HP-IB Remote Control System, Overview

Necessary equipment

1. HP 4294A precision impedance analyzer and accessories necessary for measuring test samples

2. HP-IB system controller

You can use HP 4294A as a system controller. To use only HP Instrument BASIC without using an external computer, set HP 4294A in system contr oller mode. For details , see Chapter 11 , “Using HP Instrument BASIC.”

To use an external computer as a system controller, either HP Vectra PC (or an IBM PC compatible) on which an HP-IB interface such as HP 82341D or the like is mounted or HP 9000 series 700 on which an HP-IB interface such as HP E2071D is mounted is required. In either case, software such as HP BASIC for Windows or the like is required so as to control this unit through the HP-IB. Besides series 700, HP 9000 series 300 may be used, but several peripheral devices are required in that instance.

To use an external computer as a system controller, a. set HP 4294A in addressable only mode.

b. Set the HP-IP's address to 17.

Chapter 2 27

Remote Control, Overview

HP-IB Remote Control System, Overview

The system size you can set up

• You can connect up to 15 devices with a single HP-IB system.

• The length of a cable that connects a device with another must be not more than 4 meters. Make the total length of connection cables u sed in a single HP-IB system not more than 2 meters times the number of devices (count the controller as one device). You cannot set up a system makeup in which the total cable length exceeds 20 meters.

• Limit the number of connectors attached to a single device up to 4. Attaching 5 connectors or more exerts an excessive force on them and may cause a failure.

• Star, linear, and combinational cable configurations are allowed. There must be no loop.

Controller

A device that can permit talking (outputting data) and listening (receiving data) is called a controller as against an HP-IB device.

The active controller, if connected with two or more controllers, can control other devices on the bus. A single controller only among multiple controllers can be active at a time. The active controller can pass control to another controller by use of the PASS CONTROL command.

When the power of the system controller is turned on, it becomes the active controller. When another controller is active, the system controller can execute “ABORT <select code>” so that it becomes an active controller anytime.

Device selector

HP-IB device control is carried out by receiving comm ands f rom the activ e con troller. The active controller can work the device selector to select a target device.

HP Instrument BASIC is connected with HP 4294A by way of the built-in interface within HP 4294A. The interface select code of the built-in interface is set to 8 so as to distinguish it from the external select code 7.

Since this unit alone is connected with the built-in interface, any address from “00” through “30” may be used to specify the analyzer put under the internal connection from Instrument BASIC. In this unit, address “00” is used so that the device selector turns to “800”.

Remote Control, Overview

Sending HP-IB Command Messages

HP-IB commands

HP-IB commands can be grouped into the two classes given below.

IEEE common commands

Commands defined by IEEE488.2

HP 4294A commands

Commands specific to HP 4294A. All the measurement functions and some general-purpose functions are covered.

Message syntax

Here follows the description of the syntax to be used in sending program messages by the HP-IB. A program message is a message you send from an external controller to a measuring instrument. The content of a program message is made up of a series of commands that are properly set off and terminated by delimiter and a message terminator.

Uppercase letters and lowercase letters

The difference between uppercase letters and lowercase letters are disregarded.

Program message terminator

A program message must terminate with one of three program message terminators; <new line>, <^END>, or <new line><^END>. <^END> means that EOI turns to the active level on the HP-IB interface as soon as the immediately preceding data byte is sent out. For example, the OUTPUT statement of HP BASIC automatically sends a message terminator next to the last data byte.

Parameters

A space (ASCII code 32) must be put between the last command mnemonic and the first parameter.

To send two or more parameters by a single command, each parameter must be delimited by a comma (,).

A message including two or more commands

T o send two or more commands within a single message, each command must be delimited by a semicolon (;). An example is given below in which the “PRES” command and the “*CLS” command are sent within a single message.

OUTPUT 717;"PRES;*CLS"

Setting a Sweep Condition

Setting a sweep parameter

Choose a sweep parameter from among the oscillator frequency, oscillator level, and DC bias level. To set the parameter, use the com m a nd given below.

• “SWPP” on page 401 The following settings of sweep condition will be memorized with respect to each

parameter chosen above.

Setting a sweep range

To set a sweep range, use one of two ways, those are, by means of specifying the central value and the span of the sweep range or by means of specifying the start point and the endpoint of the sweep range. To specify the central value and the span, use the commands given below.

• “CENT” on page 237

• “SPAN” on page 394 To specify the start point and the end point, use the commands given below.

• “STAR” on page 396

• “STOP” on page 398 To set the number of measurement points within the sweep range, use the command given

below.

• “POIN” on page 356

Setting sweep time

To set sweep time, use the command given below.

• “SWET” on page 400 You can set the point delay time (waiting time for measurement start at each measurement

point) and the sweep delay time (waiting time for sweep start at each sweep). To set them, use the commands given below.

• “PDELT” on page 352

• “SDELT” on page 378

Setting a sweep direction

To set a sweep direction, use the command given below.

• “SWPT” on page 401

Chapter 3 39

Setting Measurement Conditions

Setting the On-screen Arrangement

You carry out most of the settings of on-screen arrangement independently for trace A and trace B. Making settings of on-screen arrangement will take effect on an active trace. Thus you need to use the command given below so as to properly switch the active trace settings from one trace to another.

• “TRAC” on page 409

Setting the way of displaying a trace

You can select one of two ways of displaying traces A and B, those are, laying one trace over another on the same area or horizontally splitting the screen into two halves to display traces separately. In laying one trace over another, you can cause an inactive trace to disappear. To make these settings, use the commands given below.

• “SPLD” on page 395

• “HIDI” on page 274 If the results of measurement are stored in a memory trace (to be carried out by use of the

“DATMEM” command on page 244), then set a trace to display by use of the command given below.

• “DISP” on page 258 To turn on the function for accumulating a group of measurement results over another

without updating the display of trace of each, use the command given below.

• “ACCUD” on page 223

NOTE The parameters set by use of the “SPLD” command and the “ACCUD” command are

common to traces A and B.

If a phase is used as the measurement parameter, you can select a unit for the phase to display. You can also specify whether or not to display extended phases (not repeatedly displaying phases out s i de the range from -180 ° to +180 °). To make these settings, use the commands given below.

• “PHAU” on page 353

• “EXPP” on page 271 If a scalar value is used as the measurement parameter, you can set an of f set for the data to

be displayed in a data trace by use of the command given below.

• “DATOVAL” on page 244

40 Chapter 3

Setting Measurement Conditions

Setting the On-screen Arrangement

Setting a display scale

If both a data trace and a memory trace are displayed concurrently, you can separately set different scales to the data trace and the memory trace, so use the commands given below to specify whether to use the same scale for both the data trace and the memory trace, or specify which trace to set a scale to, data trace or memory trace (when not using the same scale).

• “SCAC” on page 374

• “SCAF” on page 374

NOTE The commands above are closely related to displaying a trace, that is, there can be

instances in which executing the commands above elsewhere than setting a proper display trace causes an error, changing the settings of a trace to display also changes some other items in a linked manner, and the like. So you need to be careful in deciding the sequence of executing commands in writing a program.

Three ways of setting a display scale are available depending on the display format to be set by use of the comma nd given below. So you need to set a display format before setting a display scale,

• “FMT” on page 272

NOTE The display format you can choose varies depend ing on measurement parameters.

NOTE Settings for a display scale and a display format are set for each parameter. That is, the

resultant settings become those for the parameters that has been selected in the active trace at the time of making these settings. (not the settings for trace A or trace B.)

Here follow the descriptions of individual methods.

In an instance of linear/log Y axis format

Since the display scale of the X axis depends on the sweep settings, set the display scale of the Y axis (the axis for the measurement parameter) only. To set the scale, use the scale parameters to be set by use of the commands given below.

• “SCAL” on page 375

• “REFP” on page 362

• “REFV” on page 363

• “TOPV” on page 408

• “BOTV” on page 233 In the case of a log Y axis, however, you make the settings by use of the “TOPV”

command and the “BOTV” command only. The relation between the commands and the scale parameters are as shown in Figure 3-1.

In an instance of a polar chart format

Make the settings by use of the full-scale value (the value of the outermost circle) alone. T o make the settings, use the command given below.

• “REFV” on page 363

In an instance of a complex plane format

Set the scale parameters by use of the commands given below.

• “SCAL” on page 375

• “REFX” on page 364

• “REFY” on page 364 The center line of the grid along the X axis and that along the Y axis are always used as the

lines for the reference values, and you cannot change them. The relation between the commands and the scale parameters are as shown in Figure 3-1.

Setting Measurement Conditions

Combining Two or More Sweep Conditions (List Sweep)

Combining sweep condition setting segments involved with up to 18 identical sweep parameters allows you to carry out a sweep (list sweep). To carry out a list sweep, prepare a table of segments.

At the start and the end of making a table, send the comm ands given below.

• “EDITLIST” on page 267

• “EDITDONE” on page 267

NOTE With the “EDITDONE” command not executed, the settings resulting from making,

editing, and deleti ng by us e of the comman ds giv en below wi ll not ta ke ef fect. (The t able to be used in carrying out a list sweep is left as it was before the execution of the “EDITLIST” command.)

Making/editing a segment

To make a new segment, use the commands given below. The “SADD” command adds a segment so that you can edit them. To make settings of the parameters of a segment, use the commands for setting the identical parameters described in “Setting Measurement Signals” on page 38, “Setting a Sweep Condition” on page 39 and “Setting Averaging” on page

43. After having set the parameters, send the “SDON” command to finish setting the segment.

• “SADD” on page 368

• “SDON” on page 378 Each segment is assigned a segment number (a row number in the table) so as to be used

for specifying a segment to be set, changed or deleted. To specify a segment number to be worked on, use the command given below.

• “SEGM” on page 387 Executing the “SADD” command makes an additional insertion under the line of a

specified segment (if not specified, the segment to be worked on at the time of executing the command involved), and the added segment becomes the target of setting. Thus you don't need to specify segment numbers in using the “SADD” command to make a new table by adding se gmen ts i n a s equ ence you intend. You need to specify a segment number only when adding a segment at an opt ional position of an existing table.

T o change the settings of the parameters for the existing segments, use the command given below to make a specified segment (if not specified, the segment to be work ed on at the time of executing the command involved) changeable. After having changed the parameters, send the “SDON” command to finish changing segments.

table that includes the limits of sweep ranges (segments) defined by start points and endpoints. At the start and the end of making a table, send the commands given below.

• “EDITLIML” on page 267

• “LIMEDONE” on page 282

NOTE With the “LIMEDONE” command not executed, the settings resulting from making,

editing, and deleting by use of the commands giv e n below will not take effect. (The limit line table is left as it was before the execution of the “EDITLIML” command.)

Making/editing a segment

To make a new segment, use the command given below. This command adds a segment and makes it ready to be edited.

• “LIMSADD” on page 286 To set a segment's range (a start point and an end point), use the commands given below.

• “LIMSTAR” on page 290

• “MKRLIMSTAR” on page 308

• “LIMSTOP” on page 292

Setting the Limit Test Functions

To turn on or off the ranges for limiting individual segments, use the command given below.

• “LIMSTEST” on page 291 After having set the parameters, send the command given below to finish setting segments.

• “LIMSDON” on page 287 Each segment is assigned a segment number (a row number in the limit line table) so as to

be used for specifying a segment to be set, changed, or deleted. To specify a segment number, use the command given below.

• “LIMSEGM” on page 289 Executing the “LIMSADD” command makes an additional insertion under the line of a

specified segment (if not specified, the segment to be worked on at the time of executing the command involved), and the added segment becomes the target of setting. Thus you don't need to specify segment numbers in using the “LIMSADD” command to make a new table by adding se gmen ts i n a s equ ence you intend. You need to specify a segment number only when adding a new segment at an optional position of an existing table.

To change the settings of the parameters for existing segments, use the command given below to make a specified segment (if not specified, the segment to be work ed on at the time of executing the command involved) changeable. After having changed the parameters, send the “LIMSDON” command to finish changing segments.

Adapter Setting

To select an adapter, use the command given below.

• “E4TP” on page 266 If you select any alternative other than NONE, you need to measure the data shown in the

table below so as to calculate setup data for the adapter selected.

Adapter Phase Open Short Load

NONE Unnecessary Unnecessary Unnecessary Unnecessary 4TP 1M Necessary Unnecessary Unnecessary Necessary 4TP 2M Necessary Unnecessary Unnecessary Necessary 7mm 42942A Necessary Necessary Necessary Necessary PROBE 42941A Necessary Necessary Necessary Necessary

To measure data, use the command given below.

• “ECAL{P |A|B|C}” on page 266 Y o u measure several data items by use of the command above, execute the command given

below to calculate setup data for the adapter selected, then store them in non-volatile memory (EEPROM).

• “ECALDON” on page 266

NOTE If you execute the “ECAL{P|A|B|C}” command in a manner that measures unnecessary

data, an error occurs, and the command is ignored.

To suspend the work above, execute the command given below.

• “ECALQUI” on page 267 A sample program for adapter setting is shown in Example 4-1. This program is given a

file name adapter.bas and is stored in the sample program disk. This program selects 7mm 42942A for adapter setting, measures phase data, open data,

short data, and load data, then stores them in non-volatile memory. Lines 40 to 100 These lines distinguish between the external controller and Instrument

BASIC, and set the HP-IB address and the select code. Line 110 This line substitutes the adapter selection to the variable Ad apter$. Lines 130 to 160 These lines reset the HP 4294A, then set the adapter s election to the

variable Adapter$. Lines 180 to 190 These lines set 1 to bit 8 of the instrument event status register (the bit

for completion of the measurement of calibration data and

compensation data) and to bit 2 of the service requ est enable register

so as to use SRQ. Lines 210 to 310 These lines measure phase data, open data, short data, and load data by

Lines 330 to 350 These lines calculate setup data and store them in no n-volatile

memory.

Lines 360 to 380 These lines indicate the message of completion and terminate the

program.

Here follows the description of FNAdap_setup, a data measurement sub-program for calculating setup data, shown in lines 420 to 800.

Line 450 This line clears the status byte register. Lines 460 to 470 These lines prompt for the connection for the measurement specified

Lines 490 to 500 These lines set the target of branch for an SRQ interrupt to make the

SRQ interrupt effective.

Lines 510 to 600 These lines send the commands to execute the measurement specified

by Standard$. Line 620 This line waits for measurement to fi nish. Lines 640 to 740 These lines check whether an error occurs during measurement. If no

error occurred, then these lines indicate the message of measurement

completion and returns a 0 as the return value from the sub-program. If

an error occurred, then these lines indicate an error message, execute

the command that suspends data measurement, and return -1 as the

return value from the sub-program. Lines 760 to 780 These lines are steps for any key other than the y key pressed in

response to line 470. These lines execute the command that suspends

data measurement, then return -1 as the return value from the

sub-program.

User Calibration

Selecting either 7mm or PROBE in setting the adapter allows you to use user calibration functions. To turn on the user calibr ation functi ons or of f , u se the co mmand given below. If no user calibration coefficients have been retained, the user calibration functions cannot be turned on.

• “CALST” on page 236 To measure open data, short data, and load data for calculating the user calibration

coefficients, use the command given below.

• “CAL{A|B|C}” on page 234

NOTE User calibration data and fixture compensation data are measured either at fixed points

preset by HP 4294A (fixed measuremen t po ints) or at sweep measurement points set at the time of command execution (user measurement points). In the case of the former, the compensation coefficient at a sweep measurement point is obtained by interpolation. To select points for measuring data, use the “CALP” command on page 235.

To set standard values to be used in measuring these data, use the commands given below.

• “DCALOPEN{G|C}” on page 246

• “DCALSHOR{R|L}” on page 247

• “DCALLOAD{R|L}” on page 245 After having measured individual data, you execute the command given below to calculate

the user calibration coefficient and to store it in volatile memory (RAM).

• “CALDON” on page 234

NOTE To calculate the user calibration coefficient, all of the open data, short data, and load data

are required. If you execute this command before the measurement of data is not fully completed, an error occurs and the command is ignored.

To suspend the work above, execute the command given below.

• “CALQUI” on page 235

Chapter 4 57

Getting Ready For Accurate Measurement

User Calibration

To read open data, short data, or load data measured, use the command given below.

• “OUTPCALC{1-3}?” on page 328 You can calculate the user calibration coefficients by entering open data, short data, and

load data (data read by use of the command above, or the like). To enter data, use the command given below.

• “INPUCALC{1-3}” on page 276

NOTE Enter data after setting the standard values, because the standard values used in measuring

the data is needed to calculate user calibration coefficients.

NOTE To make use of the input data, you need to enter all of open data, short data, and load data.

At the instant when all the data are entered, the calibration coefficient is automatically calculated and stored in volatile memory. So you don't need to execute the “CALDON” command if you enter all the data.

NOTE Enter data after having made settings identical with the data measurement points (fixed

measurement points, user-selected measurement points) set at the time the input data are acquired. In addition, in the case of the user-selected measurement points, enter data after having made sweep settings identical with the data measurement points.

Example 4-2 shows a sample program for measuring data to be used for calculating a user calibration coefficient. This program is given a file name user_cal.bas and is stored in the sample program disk.

You enter standard values for open data, short data, and load data, then this program measures open data, short data, and load data, calculates the user calibration coefficient, and stores it in volatile memory.

Lines 50 to 110 These lines distinguish between the external controller and Instrument

BASIC, set the HP-IB address and the select code.

Line 120 This line substitutes the selection of data meas urement points to the

variable Cal _point$.

Lines 160 to 190 These lines reset the HP 4294A, then set data measurem ent points to

Cal_point$.

Lines 230 to 280 These lines use the sub-program Inp_data to acquire standard values

you enter to be used as open data, short data, and load data.

Lines 290 to 340 These lines get the standard values you entered ready for subsequent

use. The open standard capacitance needs to be in femtofarad, so these lines make necessary conversion.

Lines 380 to 390 These lines set 1 to bit 8 of the instrument event status register (the bit

for the completion of the measurement of calibration data and compensation data) and to bit 2 of the service requ est enable register so as to use SRQ.

Lines 410 to 480 These lines measure open data, short data, and load data by use of the

sub-program FNUser_cal. If an error is detected after respective measurement, the program is terminated.

Lines 500 to 520 These lines calculate the user calibration coefficient and store it in

volatile memory. Lines 530 to 540 These lines indicate the message of completion and terminate the

program. Here follows the description of FNUser_cal, a data measurement sub-program for the user

calibration, shown in lin es 580 to 920. Line 610 This line clears the status byte register. Lines 620 to 630 These lines prompt for the connection for the measurement specified

by Standard$ and wait for you to press the y key and the return key. Lines 650 to 660 These lines set the target of branch for an SRQ interrupt to make the

SRQ interrupt effective. Lines 670 to 740 These lines send the commands to execute the standard measurement

specified by Standard$. Line 760 This line waits for measurement to fi nish. Lines 780 to 880 These lines check whether an error occurs during measurement. If no

error occurred, then these lines indicate the message of measurement

completion and return 0 as the return value from the sub-program. If

an error occurred, then these lines indicate an error message, execute

the command that suspends data measurement, and return -1 as the

return value from the sub-program. Lines 900 to 920 These lines are steps for any key other than the y key pressed in

response to line 630. These lines execute the command that suspends

date measurement, then return -1 as the return value from the

sub-program. Here follows the description of the sub-program Inp_data for entering data shown in lines

980 to 1090. Line 1000 This line makes a return to the start line of input, if an error occurs due

to an invalid input or the like, so that you can make entries again. Lines 1020 to 1030 These lines prompt you to enter a data item specified by Mes$, and

wait for you to enter it. Lines 1040 to 1060 These lines indicate the value entered, and wait for you to press either

the y key or the n key to notify whether the input is correct or not. Line 1070 This line makes a return to the start line of input if any key other than

the y key is pressed in response to line 1060.

Fixture Compensation

To turn on or off the open/short/load compensation of the fixture compensation functions, use the command given below. You can set open/short/load compensation separately. But if no compensation coefficients are retained, the functions cannot be turned on.

• “COMST{A|B|C}” on page 241 To measure open data, short data, and load data for calculating compensation coefficients

in open/short/load compensation of the fixture compensation functions, use the commands given below. Executing these commands calculates fixture compensation coefficients of measured data and stores them in volatile memory (RAM). In addition, the compensation function for measured data is turned on.

• “COM{A|B|C}” on page 240

NOTE User calibration data and fixture compensation data are measured either at fixed points

preset by HP 4294A (fixed measuremen t po ints) or at sweep measurement points set at the time of command execution (user-selected measurement points). In the case of the former, the compensation coefficient at a sweep measur ement point is ob tained by interpolation. To select points for measuring data, use the “CALP” command on page 235.

To set standard values to be used in measuring these data, use the commands given below.

Example 4-3 shows a sample program for measuring data to be used for calculating a fixture compensation coefficient. This program is given a file name com_meas.bas and is stored in the sample program disk.

You enter standard values for open data, short data, and load data, then this program measures open data, short data, and load data at fixed measurement points preset by HP 4294A, and stores the measured data and the defined standard values in a flash disk (non-volatile memory disk) by giving the data the filename COM_DATA and STD_VAL, respectively.

Lines 60 to 150 These lines distinguish between the external controller and Instrument

BASIC, and set the HP-IB address and select code. In the case of

Instrument BASIC, flash memory is used as the storage unit. Lines 160 to 180 These lines substitute the selection of data measurement points to the

variable Cal_point$, the name of the file to be retained measured data

to the variable File$, and the name of the file to be retained standard

value to the variable Std_file$, respectively. Lines 220 to 250 These lines reset the HP 4294A, then substitutes the data measurement

points to Cal_point$. Lines 290 to 340 These lines use the sub-program Inp_data to acquire standard values

you enter to be used as open data, short data, and load data. Lines 350 to 400 These lines set the standard values. The open standard capacitance

needs to be in femtofarad, so these lines make necessary conversion. Lines 440 to 450 These lines set 1 to bit 8 of the instrumen t event s tatus register (the bit

for the completion of the measurement of calibration data and

compensation data) and to bit 2 of the service request enable register

so as to use SRQ. Lines 470 to 540 These lines measure open data, short data, and load data by use of the

sub-program FNFixt_comp. If an error is detected after respective

measurement, the program is terminated. Lines 580 to 740 These lines decide on the IEEE 64-bit floating-point format for the

data transfer format, read open data, short data, and load data, and

store them in the arrays Com_o(*), Com_s(*), and Com_l(*)

respectively. Lines 790 to 810 These lines delete a file named File$ if already exists. Lines 830 to 860 This lines create a file named File$ and write the data stored in the

Fixture Compensation

Example 4-4 shows a sample program that takes in data for fixture compensation to use them. This sample program is given a file name com_inpu.bas and is stored in the sample program disk.

This program reads open data, short data, and load data from the files (COM_DATA and STD_VAL) retained by the program shown in Example 4-3, and sets them.

Lines 50 to 140 These lines distinguish between the external controller and Instrument

BASIC, and set the HP-IB address and the select code. In the case of Instrument BASIC, flash memory is used as the storage unit.

Lines 150 to 180 These lines substitute the selection of data measurement points, the

number of compensation data measurement points (100 for fixed measurement points), the name of the file for reading compensation data, and the name of the file for reading standard value, respectively to the variables Cal_point$, Point, File$ and Std_file$.

Lines 220 to 250 These lines reset the HP 4294A, then assign the data measurement

points to Cal_point$.

Lines 290 to 310 These lines read open data, short data, and load data from the file

named File$ in sequence as written in Example 4-3, and store them in the arrays Com_o(*), Com_s(*), and Com_l(*) respectively.

Lines 330 to 350 These lines read open/short/load standard values from the file named

Std_file$ in sequence as written in Example 4-3, and store them in the variables Open_g, Open_c, Short_r, Short_l, Load_r, and Load_l respectively.

Lines 390 to 440 These lines set the standard values. The open standard capacitance

needs to be in femtofarad, so these lines make necessary conversion.

Line 480 This line decides on the IEEE 64-bit floating-point format for the data

transfer format.

Line 490 This line calculates data size from Point, and creates a header to be

used at the time of data transfer.

Lines 510 to 580 These lines enter data for open/short/load compensation. When the

data are entered, the open/short/load compensation of the fi xture compensation functions is turned on.

This chapter describes how to generate a trigger to start a measurement and how to detect the completion of a measurement.

Starting a Measurement (Trigger) and Detecting the Completion of a Measurement (End of Sweeps)

Triggering a Measurement (Starting a Measurement)

Trigger system

The trigger system of the HP 4294A has 3 states: “Idle”, “Waiting for Trigger”, and “Measurement” as shown in Figure 5-1.

Figure 5-1 Trigger system

The state transitions in the trigger system are described below. Executing the following command causes a transition to the “Idle” state.

• “HOLD” on page 274 Setting the number of sweeps using the following command causes a transition to the

“Waiting for Trigger” state.

Command Number of measurements

“SING” on page 389 Once “NUMG” on page 319 Specified number of times “CONT” on page 241 Continuous (until “HOLD”, “SING”, or “NUMG” is executed)

Generating a trigger in the “Waiting for Trig ger” state causes a transition to the “Measurement” state and performs a measurement (one or more sweeps). The method to generate a trigger varies depending on the trigger source setting. To set the trigger source, use the following command.

• “TRGS” on page 411

The state transition after the completion of each sweep varies depending on the sweep count setting.

Once Transitions to the “Idle” state (a in Figure 5-1). Specified number

of times Repeats a transition to the “Waiting for Trig ger” state until the

specified number of sweeps are completed (b in Figure 5-1). After the completion of the specified number of sweeps, causes a transition to the “Idle” state (a in Figure 5-1).

Step 1. Step 2.

Step 1. Step 2. Step 3.

Continuous Repeats a transition to the rigger wait state (b in Figure 5-1).

Triggering a measurement

To make measurements continuously (to automatically generate triggers continuously)

Use the “TRGS” command to set the trigger source to the internal trigger. Use the “CONT” command to set the sweep setting to the continuos sweep.

To make a measurement at any desired time (to generate a trigger from an external controller)

Use the “TRGS” command to set the trigger source to the internal trigger. Use the “SING” or “NUMG” command to execute a single sweep or the specified number

of sweeps at any desired time. Or Use the “TRGS” command to set the trigger source to the HP-IB/LAN trigger. Use the “CONT” command to set the sweep setting to the continuous sweep. Execute the “*TRG” command on page 221 or the HP BASIC TRIGGER command

(execute the group execution trigger) at any desired time.

NOTE You can use the group execution trigger (GET) when you want to trigger all devices

connected to the controller simultaneously that can be triggered.

Using the status register

Y o u can detect the state of the HP 4294A through the status register . The com pletion of one or more sweeps is indicated by the instrument event status register. To detect the completion of one or more sweeps from a program using th e information in this register, use an SRQ (service request).

To detect the completion of one or more sweeps using an SRQ, use the commands below.

• “*SRE” on page 220

• “ESNB” on page 271 The procedure is as follows:

Step 1.

Step 2. Step 3.

Figure 5-2 SRQ generation sequence (at the end of one or more sweeps)

Make the setting so that the HP 4294A generates an SRQ when the sweep completion bit in the instrument event status register is set to “1.”

Generates a trigger to start one or more sweeps. Performs the interrupt processing in the program when an SRQ is generated.

Example 5-1 is a sample program using an SRQ to detect the completion of sweeps. This program is stored on the sample program disk as the swp_srq.bas file.

This program sets the sweep averaging factor to 4, makes the SRQ setting, and then performs 4 sweeps. When an SRQ is generated at the completion of the sweeps, the program displays the completi on message and th en finishes.

Using the *OPC? command

The “SING” command on page 389 and “NUMG” command on page 319 are overlap commands, whose execution is finished at the completion of one or more sweeps. Therefore, if you start one or more sweeps using these commands, you can detect the completion of them using the following command.

• “*OPC?” on page 219 Example 5-2 shows a sample program to detect the completion of a sweep using the

“*OPC?” command. This program is stored on the sample program disk as the swp_opc.bas file.

This program starts a sweep using the “SING” command, waits for the completion of the execution of the “SING” command using the “*OPC?” comm and (the completion of a single sweep), displays a message at the completion of the sweep, and then finishes.

Lines 20 to 60 Identifies the external controller and Instrument BASIC and sets the

HP-IB address. Line 80 Sets the trigger source to the internal trigger. Lines 90 Starts a single sweep. Lines 110 to 120 Executes the “*OPC?” command and waits for 1 to be read out (the

completion of the sweep). Line 130 Displays the sweep completion message.

Example 5-2 Detecting the completion of a sweep using the “*OPC?” command

10 DIM Buff$[9] 20 IF SYSTEM$("SYSTEM ID")="HP4294A" THEN 30 ASSIGN @Hp4294a TO 800 40 ELSE 50 ASSIGN @Hp4294a TO 717 60 END IF 70 ! 80 OUTPUT @Hp4294a;"TRGS INT" 90 OUTPUT @Hp4294a;"SING" 100 PRINT "Waiting..." 110 OUTPUT @Hp4294a;"*OPC?" 120 ENTER @Hp4294a;Buff$ 130 PRINT "Sweep Complete" 140 END

Inserting a wait

You can make a setting so that the controller waits for the completion of one or more sweeps performed by the HP 4294A (for example, in the case of HP BASIC, use the WAIT command). This method is simple but, if you set an inappr opriate wait, unexpected errors could occur.

6 Reading/Writing Measurement Data

This chapter describes how to read or write measurement data and h ow to obtain level monitoring and limit test results.

Reading/Writing Measurement Data

Data Transfer Format

The format applicable when you read measuremen t param e ter settings from HP 4294A (as when you read the sweep start point with “STAR?”) is the ASCII format, regardless of which data transfer format has been specified.

You can select either the ASCII format (default) or one of the binary formats for reading measurement data, waveform analysis result and so on from HP 4294A (as when you read data trace array with “OUTPDTRC?”). As for binary formats, the IEEE 32-bit floating point format, IEEE 64-bit floating point format, and MS-DOS personal computer format are available to choose from. You can select the appropriate format f or your controller from these options. Use the following commands for selecting a desired data transfer format:

Data Transfer Format Commands

IEEE 32-bit floating point format “FORM2” on page 273 IEEE 64-bit floating point format “FORM3” on page 273 ASCII format (Default) “FORM4” on page 273 MS-DOS personal computer format “FORM5” on page 273

ASCII format (Form 4)

When you select the ASCII format as data transfer format, numbers are transferred as ASCII bytes, each of which corresponds to one of th e fo rmats shown below. Note also that numbers are separated from one another with a comma (“,”) in accordance with the IEEE488.2 specification.

NOTE Each numeric data character string is different in length from others. Before extracting

each piece of data from character strings, you must remember, therefore, that commas do not always appear at the same locations.

• Integer Format

Figure 6-1 shows this format. Numbers are expressed as integers. For example, 201 is expressed as “+201” or “201.”

Figure 6-1 Integer Format

Line 110 to 120 Substitutes the trace selected as active trace and the number of

measurement points to the corresponding variables (Act_trc$, Nop), respectively.

Line 140 to 150 Specifies the IEEE 64-bit floating point fo rmat as da ta transfer format,

and sets the number of measurement points to Nop. Lines 170 to 180 Holds the trigger and sets the active trace to Act_trc$. Lines 190 to 200 Clears error queue and specifies memory trace as the trace to be

displayed. Lines 210 to 220 Checks for errors. Line 240 An error message appears if error No.34 (error that occurs if an

attempt is made to use memory trace when no data has been stored as

memory trace). Then, program execution stops without performing

any operations. Lines 260 to 270 Executes a memory trace array read command, reads the header, and

substitutes it to “Header$” (variable). Line 280 Reads the memory trace array and stores it in “Trc(*)” (array variable).

Binary data must be read without being formatted. Therefore, an I/O

path (@Binary) that has been set to read without being formatted is

used. Line 290 Reads the terminator (LF^EOI) provided at the end of the data. Line 310 Specifies data trace as the trace to be displayed. Lines 320 to 330 Writes “Trc(*)” to the data trace array. To do this, a data trace array

write command with “Header$” (header) is sent first. Next, “Trc(*)”

(data part) is sent. When the data part is sent, an I/O path (@Binary)

that has been set to send without being formatted is used.

When to read/write data

If a read command is executed while sweep is in progress, the data available when the command execution starts is read. To ensure accuracy of data you obtain, be sure to wait until the current sweep is complete before executing a read command. When you consider the time it takes for your program to be executed to completion, you need to synchronize the execution of a read command with the completion of the current sweep. To do this, use the status report structure and the “*OPC?” command on page 219. See “Waiting for the Completion of One or More Sweeps (Detecting the Completion of a Measurement)” on page 74 for more information.

To write data properly, you need to execute a write command while no sweep is in progress. You can write data while sweep is in progre ss. In t his case, h owever, the data you write will be overwritten. You can hold sweep by executing the “HOLD” command on page 274.

7 Processing Measurement Results

This chapter describes how to process measurement results using the marker function, the equivalent circuit analysis function, the trace bandwidth analysis function, and analysis commands.

Processing Measurement Results

Reading Measurement Data at Specific Measurement Points (Using the Marker Function)

You can use the marker to read measurement data at specific points on the trace or search for the point that meets a specific condition such as the maximum value. You need to use the following command to turn ON the marker before using it.

• “MKR” on page 305 You can use the main marker (marker No.0; hereafter referred to as the marker) when you

execute the above command. To use one or more submarkers (markers No.1 through 7), use the following command to turn them ON:

• “SMKR{1-7 }” on page 390 You can also use the ∆ marker to obtain the result of subtraction of the ∆ marker-specified

value from the marker or submarker-specified value or the dif ference between these values. Use the following command to turn ON the ∆ marker:

• “DMKR” on page 259 When you turn ON a submarker or the ∆ marker, it appears where the marker is currently

located.

Moving the marker

Moving the marker to specific points

Use the following command to move the mar ker, one of the submarkers, or the ∆ marker to a desired measurement point or sweep parameter value on the trace:

Specific Measurement Point Specifi c S w eep Parameter Value

Marker “MKRP” on page 312 “MKRPRM” on page 313 Submarker “SMKRP{1-7}” on page 391 “SMKRPRM{1-7}” on page 392

Marker “DMKRP” on page 261 “DMKRPRM” on page 262

∆

Moving after search for positions that meet specific conditions

Use the following command to search for an d move the marker to specific positions on the active trace such as maximum value, minimum value, peak, and measurement parameter value (target) specified with the “SEATARG” command (page 385):

• “SEAM” on page 379 When the active trace has two or more peaks or targets, the search is made as shown below

after execution of the above command. Peak Maximum peak (minimum peak if the peak has been defined as

negative peak) Target Targ et closest to the current marker position You can use the following commands to sequentially search for the remaining peaks or

targets:

Sample program for using the marker function

Example 7-1 shows a sample program for using the marker function. This program is available under the filename of “marker.bas” in the sample program disk.

This program performs sweep once, uses the marker function to search for the maximum peak and the minimum negative peak in the 10-100 MHz range, provides a submarker at each of these peaks, and reads and displays the submarker-specified values.
