Introduction

Document Concepts and Usage

This manual provides an intro duction to writing BASIC programs for the HP 4395A

Network/Spectrum/Impedance Analyzer (analyzer). To reduce the time required for you to

learn how to write programs for the analyzer,the examples shown in this guide are supplied on

sample disks. You can perform each example sequentially or you can select the examples that

apply to your immediate needs and learn those techniques. Use the table of contents and the

index to quickly lo cate these examples.

Also, depending upon your experience in writing BASIC programs using HP-IB commands,

you maywant to do one of the following:

1. If you are an experienced programmer and ha

can scan the examples in this guide to nd out ho

ve programmed HP-IB systems before, you

w the analyzer can b e used in y

our

system.

2. If you are not experienced in programming for HP-IB instrumen

to read this manucal from the beggining. Chapter 1 will help y

ts, we recommend you

ou greatly, providing

programming basics.

3. Sample programs will giveyou a hintonhow to use an HP-IB command in your program.

For detailed information on an HP-IB command, see Chapter 11.

4. The HP 4395A provides the HP Instrument BASIC feature. If you use the HP Instrument

BASIC for the rst time, see Chapter 9 which describes the usage of the feature.

Overview of the HP-IB Remote Control System

This chapter provides information on how to congure the HP-IB remote-control system and

the basic use of the HP-IB commands. In the examples used in this man

commands are the simple HP-IB commands. Note that no SCPI commands are a

for the HP 4395A. Chapter 11 describ es all the HP-IB commands that are a

ual, most of the

vailable

vailable for the

HP 4395A.

What is HP-IB?

The Hewlett-Packard Interface Bus (

hp-ib

) is used for remote

control of the HP 4395A Network/Spectrum Analyzer (analyzer).

HP-IB is a standard for interfacing instruments to computers and

peripherals. This standard supports worldwide standards

IEEE 488.1, IEC-625, and IEEE 488.2. The HP-IB interface

allows the analyzer to be controlled by an external computer. The

computer sends commands or instructions to and receiv

es data

from the instrument through the HP-IB.

Introduction 1-1

Required Equipment

To perform the examples in this manual, you need the following equipment:

1. The analyzer and the accessories required to test a sp ecic device under test (

2. For the HP-IB system controller,

If the analyzer has the HP Instrument BASIC installed, it can be used as the system

controller.

Or,

An HP Vectra PC with HP-IB interface card (HP 82341D etc.) or an HP 9000 Series 700

computer with HP-IB interface card (HP E2071D etc.). For any computer, you need an

HP-IB control software, for example HP BASIC for windows. (You can use HP 9000

Series 200/300 computer, too).

3. Peripherals (printer, plotter, and so on) and any HP-IB instruments that are required for

your application.

4. HP 10833A/B/C/D HP-IB cables to interconnect the computer, the analyzer, and any

peripherals.

dut

).

1-2 Introduction

Controller

In the HP-IB terminology,a

device to

talk

(output data) or

controller

listen

is dened to be a device that can permit an HP-IB

(receive incoming data).

When multiple controllers exist on an HP-IB bus, only one of them can be active at a time

and can control other devices on the bus. The active controller can issue a

PASS CONTROL

command to pass control to another controller in the same HP-IB remote control system.

In a multiple-controller conguration, you can designate one of the controllers as the

controller

. The system controller becomes active by default when the system p ower is turned

system

ON. When another controller is serving as the active controller, the system controller can

issue an

ABORT

select code

to become the active controller at any time.

Device Selector

The active controller can control any of the connected HP-IB devices. To select which HP-IB

device to put under its control, the active controller uses the device selector mapp ed to that

target device. Then, the active controller can send various commands to control the b ehavior

or activity of the target device.

1. Use HP-IB cables to connect the HP 4395A with con

trollers (computers) and peripherals.

Figure 1-1. Configuration of an HP-IB Remote Control System

Figure 1-1 illustrates how HP-IB addresses are mapped to device selectors. For example, a

printer whose HP-IB address is \1" is mapp ed to device selector \701".

Introduction 1-3

The HP Instrument BASIC feature is internally connected to the HP 4395A via the built-in

interface. The interface select co de for the built-in interface is dened as \8." Thus it is

distinguished from the external select code \7."

From HP Instrument BASIC, any address ranging from \00" to \30" can b e used to

designate the analyzer, which is only the device that is connected to the built-in interface.

Throughout this manual, the address \00" is always used for the analyzer so that its device

selecter is \800."

How large a system can you

congure?



maximum of 15 devices can be connected on one bus system.



The length of cable between one device and another must be less

than or equal to four meters. The total length of cable in one bus

system must be less than or equal to two meters timesthe number

of devices connected on the bus (the HP-IB controller counts as

one device). The total length of cable must not exceed 20 meters



Star, linear, and combinational cable congurations are allowed.

There must be no lo op.



It is recommended that no more than four piggybac

be stacked together on one device. Otherwise, the resulting

structure could exert enough force on the connector moun

damage it.

Programming Measurement Sequence

This chapter provides basic pro cedures required for programming a measurement sequence.

The chaper covers:

HP-IB Commands Overview

To Program a Basic Measurement

HP-IB Commands Overview

All the analyzer's front-panel keys have a corresponding HP-IB command. By executing an

HP-IB command, you can operate the analyzer as if y

For example, Pressing

is the same as executing the HP-IB command,

ou were pressing the corresponding key.

What is HP-IB remote

mode?

Executing an

OUTPUT

statement that is addressed to the analyzer,

sets it to the HP-IB remote mo de. In the remote mo de, all the

analyzer's front-panel keys are locked out, except

puts the analyzer back in local mo de. In lo cal mo de, all

front-panel keys are enabled.

Note

In the ab ove example, the OUTPUT statement can b e written as follows if

you use it with an ASSIGN statement:

ASSIGN @Hp4395 TO 800

OUTPUT @Hp4395;"PRES"

This style might make modication of a program easier, depending howyour

program is organized.

To Execute an HP-IB Command with a Parameter

Some HP-IB commands require a numeric parameter. For example:

OUTPUT @Hp4395;"CENT 25000000" ! Set center frequency to 25 MHz.

(The space b etween the command and the numeric parameter is mandatory.)

You can program it to be entered each time the program is run. For example:

100 INPUT "Enter center frequency(Hz).";F_cent

110 OUTPUT @Hp4395;"CENT ";F_cent

Executing this gives you:

d a

Enter center frequency (Hz).

25000000

The analyzer's center frequency is set to 25 MHz.

To Execute a Query

A query command is a command that inquires an instrument informations suchas

measurement data. In general, a query command is used in an OUTPUT statement with an

ENTER statement asso ciated. Note that executing a query command does not always result

in a single numerical value; it may contain multiple values or charater strings. See Chapter 11

for details.

10 OUTPUT @Hp4395;"CNTS?"

20 ENTER @Hp4395;A

Any HP-IB command that is used with a numeric parameter can also be used as query

command. For example, the

CENT

numeric parameter

command used in the previous example,

can be combined with a?, and used as a query command as follows,

10 OUTPUT @Hp4395;"CENT?"

20 ENTER @Hp4395;A

30 PRINT A

2-2 Programming Measurement Sequence

A query command is used mostly in an OUTPUT statement followed by an ENTER

statement;the OUTPUT statement sends the query command to the HP 4395A and the

ENTER statement receive a return value from the analyzer.

The

CENT?

command returns the current center frequency, which is put intoA. Executing this

program results in the following:

d a

25000000

By interrogating the analyzer to determine the values of the start and stop frequencies, or the

center frequency and frequency span, the computer can keep track of the actual frequencies.

Programming Measurement Sequence 2-3

To Program a Basic Measurement

This section describ es how to organize the commands into a measurement sequence.

In general, the procedure for setting up measurements on the analyzer via HP-IB follows the

same sequence as performing the pro cedure manually. There is no required order, as long as

the desired frequency range, number of points, and power level are set before performing the

calibration.

In line 70, several HP-IB commands, separated by semicolon, are executed in a line. This is

the same as:

Programming Measurement Sequence 2-5

70 OUTPUT @Hp4395;"CHAN1"

71 OUTPUT @Hp4395;"NA"

72 OUTPUT @Hp4395;"MEAS S21"

73 OUTPUT @Hp4395;"FMT LOGM"

In lines 80 to 110 (setting frequency), parameters are required with the HP-IB command. To

set parameters, see \To Execute an HP-IB Command with a Parameter" later in this chapter.

In lines 140 to 240, the HP-IB program follo

ws the key strokes required to calibrate from the

front panel. This program performs a response calibration.

Line 170 requests the operator to connect a THR

U calibration standard.

Lines 180 through 220 use the status bytes to detect the completion of the THRU calibration.

Processing and Tranferring Data

This chapter illustrates how to transfer and receive data stored in the HP 4395A between the

controller via HP-IB.

Measurement data can be read out of the analyzer in the following ways:

1. The entire trace (or data for a specied number of p oints) can be read out in the following

ways:

Data arrays | In regard to the data processing ow, the following data arrays are

available.

RAWDATA ARRAYS

CALIBRATION COEFFICIENT ARRAYS

DATA ARRAYS

MEMORY ARRAYS

DATA TRACE ARRAYS

MEMORY TRACE ARRAYS

Note

When you transfer these data to HP 4395A, set HP 4395A's conguration

the same way as when you received data. Without this, you will be unable

to measure correct data. Be sure to set up CALIBRA

TION COEFFICIENT

ARRAYS.

Data format | The analyzer provides four data transfer formats.

FORM2 IEEE 32 bit oating point format

FORM3 IEEE 64 bit oating point format

FORM4 ASCII format

R

FORM5 MS-DOS



personal computer format

Depending on the format, the data transfer sp eed and the number of digits are changed.

Generally, binary data transfer (FORM2, FORM3, or FORM5) is faster than ASCI I

(FORM4).

2. Data can b e read o the trace selectiv

ely using the markers.

The presentvalue of the marker (real-imaginary data and sweep parameter) is retrieved.

For additional information on the marker functions, see Chapter 8.

Each calibration type uses only as many arrays as needed, starting with array 1, and each

array stores a specic error coecient. Therefore, it is necessary to know the type of

calibration about to b e read out: attempting to read an array not being used in the curren

Data Levels

The analyzer has the following data arrays in internal memory:

Raw data

These arrays store the results of all the preceding data processing operations. Note that the

numbers here are still complex pairs.

When the Network analyzer mo de and the full 2-port error correction are on, the raw data

arrays contain all four S-parameter measurements required for accuracy enhancement.

Error corrected data

The results of error correction are stored in the data arrays as complex number pairs.

Formatted data

This is the array of data being displayed. It reects all post-processing functions suchas

electrical delay, and the units of the array read out depends on the current display format.

Calibration coecients (Network and imp edance analyzer only)

The results of a calibration are stored arrays of calibration co ecien

ts that are used by the

error correction routines. Each array corresp onds to a sp ecic error term in the error mo del.

The calibration co ecients are read out with

OUTPCALC{1-12}?

.

xture compensation coecients (Imp edance analyzer only)

The results of a xture compensation are stored arrays of xture compensation coecien

that are used by the error correction routines. Each array corresponds to a specic

error term in the error model. The xture compensation coecien

OUTPCOMC{1-3}?

ts are read out with

Formatted data is generally the most useful, because it is the same information as that

seen on the display.However, if post-processing is not necessary

smoothing, error corrected data is more desirable. Error corrected data also giv

opportunity to load the data in

to the instrument and apply post-processing at a later time.

Synchronizing the HP 4395A with a Controller

You can use a program running on a controller to remotely instruct an HP-IB compatible

device to calibrate itself, output measurement data, p erform calculations or other tasks.

Implementing such a remote control system, however, requires you to keep the HP 4395A

synchronized with the program execution.

For example, when obtaining measurement data, the controller must wait until the HP 4395A

completes the current measurement pro cess. For calibration, the controller must wait until the

HP 4395A nishes processing the data.

You can synchronize the HP 4395A with the controller in several ways:

Use the

Use the

Use an SRQ to suspend the external controller until the completion of the sweep pro cess.

Also, you can use a

Suspending a Program Running on a Controller (*OPC)

The above code causes the controller to suspend the program execution until all preceding

commands are successfully processed and

*OPC?

returns1.

In Figure 2-2 (Chapter 1), for example, the

.

.

.

*OPC?

command is used as follows:

250 OUTPUT @Hp4395;"*OPC?" ! Wait until completed

260 ENTER @Hp4395;Dum

270 DISP "Response cal completed."

.

.

.

Using the WAIT Command of BASIC

Using the

WAIT

command of BASIC, you can have the controller wait for a particular period

of time. This is a very simple solution, but requires you to accurately measure the time

required for the HP 4395A to actually process a certain command(s).

10 OUTPUT 717;"SA"

20 WAIT 5

30 OUTPUT 717;"NA"

40 WAIT 5

50 END

Since this technique causes the controller to wait without communicating with the HP 4395A,

an improper wait time setting can result in an unpredictable error. However, using the

WAIT

command can eectively speed up the execution of your program as long as the setting is

accurate.

Figure 4-2. Sample program: Wait until the preceding command is completed.

Here is a tip: You can just issue a single EXECUTE \SING" statement to synchronize with

the completion of sweep. This is useful, for example, when you want to use the marker after a

single cycle of measurement.

80 EXECUTE "SING"

This causes the controller to wait until one cycle of sweep is completed.

90 OUTPUT @Hp4395;"MKR ON"

100 OUTPUT @Hp4395;"SEAM MAX"

Because the measurement is already completed, you can eectively use the marker.

Note that the

EXECUTE

command is supp orted for Instrument BASIC only.

Using SRQ

You can also use an SRQ to implement synchronization with the completion of sweep. This

technique is recommended when you are using an external controller. For how to synchronize

an SRQ with the completion of a sweep pro cess that uses an SRQ, refer to \ToWait for

Sweep End" in Chapter 5.

Using the *WAI Command

Note

If the active controller is an external controller, using the

cannot perfectly synchronize the controller with the HP 4395A.

The

*WAI

command prevents the HP 4395A from pro cessing any newly received commands

until it nishes processing all preceding commands. If the HP 4395A receives a new HP-IB

command during the wait, it stores the command in a buer.

What is an SRQ?

An SRQ (Service Request) is an interrupt generated by the

analyzer. The analyzer can be setup to sen

the attention of the controller. The controller can ignore the SRQ

or it can b e setup to interrupt the program using the ON INTR

commands. The Status Byte can be used to dene the specic

event that generates an SRQ (for example, the end of sweep

complete).

General Status Register Model

The analyzer has a status reporting system to report the condition of the analyzer.

Figure 5-1. General Status Register Model

The status rep orting system has a hierarchical structure as shown in Figure 5-1. When the

analyzer condition satises the particular condition, the corresponding bit of the ev

is set \1". Therefore, you can check the analyzer condition by reading the event register.

ent register

When the event register bit is set to \1", and corresp onding enable register bit is also \1", the

summary bit of the status byte register is set to \1". You can read the status byte register by

using the serial poll.

If the corresp onding bit of the service request enable register is \1", the service request (SR

is generated with the positive transition of the status b

SRQ, you can notify the controller that the analyzer is requesting service.

Event Register

Reects the correspondent analyzer condition as a bit status. These bits monitor the changing

analyzer state continuously and change the bit status as required.

You cannot change bit status by HP-IB command.

The analyzer has the following event registers:

Standard Event Status Register (ESB) Contains the summary of general processing which

includes completion of sweep. See Table 5-2 for details.

Event Status Register (ESR) Contains the information on occurrence of an op eration failure

such as a command error. See Table 5-3 for details.

Operation Status Event Register (OSR) Contains only the information that a program is

runnig and/or data is b eing transfered to the prin

yte register bit. By generating the

ter. See Table 5-4 for details.

Q)

5-2 Status Reporting System and Processing Generated Interruptions

Enable Register

The enable register selects whichevent register bits can set the bit in the summary bit of the

status byte register that is connected to SRQ generation. The register bits work like mask

bits. When you want to set a bit in the status byte register by a specic register condition,

set the corresp onding enable register to 1. This sets a 1 bit in the status byte register with a

corresponding event register bit.

Status Byte Register

If enabled event register is set to 1, the corresponding bit of the status byte register is set to

1. This register also indicates the output queue and SRQ status.

The value of the status byte register can be read by using the

SPOLL

statement or the

*STB?

query from the controller. Reading the status byte register by either command does not aect

the contents of the status byte register. Table 5-1 lists the contents of the status byte register.

the RQS bit. The

SPOLL

command reads bit 6 of the status byte register as

y the status byte register by setting the service

request enable register. For more information about SRQ, see Figure 5-6 in this chapter.

Transition Filter and Condition Register

The transition lter allows you to select which transitions of the analyzer condition will set a

bit in the event register.

When the status register has a transition lter, there is a lo

wer register called a condition

register under the event register. The transition lter is between the event register and the

condition register. The transition lter enables you to select a positive and/or negative

transition of the condition register bit to set a bit in the corresp onding ev

example, if you set the negative transition lter, a 1 is set in the ev

ent register bychanging

ent register. For

from 1 to 0 in the event register.

Figure 5-2. Transition Filter and Condition Register

Status Reporting System and Processing Generated Interruptions 5-3

For the HP 4395A, only the \Program Running" bit of the operation status register has a

transition lter. By using the transition lter, you can generate an SRQ either at the start or

the end of the program execution.

Status Bit Definitions of the Status Byte (STB)

The status bytes consist of 8-bit registers, with each bit representing a specic analyzer

condition. The value of the Status Byte can b e read by using

SPOLL(717)

statement from an

external controller. This command reads a value directly from the analyzer without being

set to remote. So, you can operate front panel keys while a controller is reading the Status

Byte. Contents of the Status Byte can also be read by using the

*STB?

command. Reading

the Status Byte does not aect the contents of the Status Byte. Table 5-1 shows contents of

How to Use the Status Registers in a Program

You can use the status registers to determine the specic analyzer status in the program. To

determine the contents of the status register, the following metho ds are used:

Read an event register directly.

Use the Service Request (SRQ).

Reading an Event Register Directly

You can read the contents of the event register directly to determine the specic analyzer

condition. Use this method if you do not need to know the timing of the event register

changes. The following procedure reads the register directly:

1. Query the event register or the condition register contents.

2. Retrieve a return value.

The list shown below is an HP-BASIC sample program using the BIT function.

Using the Trigger System in HP 4395A

This chapter describes how to control the trigger system of the analyzer.

To trigger a measurement from a controller, the following steps are commonly used:

1. Set the trigger source to:

Bus, or Internal (free run)

(In External, Video, Manual or Gate trigger, you cannot trigger from the controller, so

these sources are not mentioned in this guide.)

2. Set the number of measurements and the analyzer is initiated. You can set the number of

measurements as:

(Hold)|Single|Number of Group|Continuous

3. Generate the trigger event and the analyzer starts a measurement.

The analyzer trigger system has three states: Idle, W

aiting for Trigger, and Measurement.

Figure 6-1. Trigger System

Using the Trigger System in HP 4395A 6-1

In Figure 6-1,

1. After a

HOLD

HP-IB command execution, the analyzer returns to the \Idle" state.

2. By setting the number of measurements, the analyzer changes from the \Idle" state to the

\Waiting for Trigger" state.

3. At the \Waiting for Trigger" state, a trigger input (corresponding to the trigger source)

starts a measurement.

Bus HP-IB command

*TRG

or BASIC command

TRIGGER

triggers

measurements.

Internal (free run) There is no need for a trigger input. The analyzer starts the

measurements immediately.

4. After the measurement is complete, the next state depends on the number of

measurements.

Single goes to the \Idle" state(4-a).

Number of Groups Go es to the \Waiting for Trigger" state until the number of groups not

measured yet equals zero(4-b).

After all measurements are completed, goes to \Idle" state(4-a).

Continuous go es to the \Waiting for Trigger" state(4-b).

6-2 Using the Trigger System in HP 4395A

What can you do to

abort a measurement?

Send the command:

OUTPUT @Hp4395;"HOLD"

Note

The HP 4395A will fail in prop er measurement data transfer when it is

triggerd using the internal trigger source. If you want to transfer measurement

data to the controller, you must use either the

SING

or the

NUMG

parameter

command to synchronize the controller and the analyzer. To use these

commands, see \Using the EXECUTE Statement to Synchronize with

the Completion of Sweep" in Chapter 4 and \ToWait for Sweep End" in

is selected and the analyzer immediately starts a measurement. After the measurement, the

analyzer go es to the \Idle" state.

How can you perform

averaging?

When you set the averaging on, you must also set the number of

measurements to the same value as the averaging factor. For

example, if the averaging factor is 10, replace line 60 as follows:

60 OUTPUT @Hp4395;"NUMG 10"

How can you wait for a

measurementtobe

completed?

When you want to return the measurement data to the controller,

you must wait for the measurement to be completed. For details,

see Chapter 4.

IBASIC Commands for the 8-bit I/O Port Control

IBASIC commands related to the 8-bit I/O port are dened as follo ws:



WRITEIO 15,0;

Outputs 8-bit data through lines OUT 0 to OUT 7. The OUT 0 signal is

the LSB (least signicant bit) and the OUT 7 signal is the MSB (most

signicant bit).



READIO(15,0)

Inputs 4-bit data through lines from IN 0 to IN 3 to the HP 4395A's

memory and returns the data to an IBASIC program. The IN 0 signal is

the LSB and the IN 3 signal is the MSB.

HP-IB Commands for the 8-bit I/O Port Control

The HP-IB commands related to the parallel I/O ports are described belo



OUT8IO

Outputs 8-bit data through lines OUT 0 to OUT 7. The OUT 0 signal is the

7-4 Using the I/O Port

The 24-bit I/O Port

The HP 4395A's 24-bit I/O port has four independent parallel ports for data input or

output, and several control signal and p ower lines. All signals are TTL level. The data I/O

port consists of 2 pairs of 8-bit output ports and 2 pairs of 4-bit two-ways p orts. If you use

these ports together, you can use them as a 24-bit output port or as an 8-bit input port at

maximum. The I/O signal is initialized to use negative logic, but it can be set to use positive

logic using an HP-IB command. The control signal lines consist of measurement completion

output, PASS/FAIL output of limit testing results, control signal outputs for handshaking,

and so on.

Note

A 36-pin cable (part number: 04278-61650) is available if you cannot connect

the device directly to the connectors of the 24-bit I/O port interface on the

rear panel. This cable enables a 1m cable extension of this interface.

Using the I/O Port 7-5

Control Signal Lines

The I/O p orts include 10 types of output signal lines and one input signal line. These control

signals are TTL-compatible (excluding the power supply line). Each of them are describ ed

below.

Port C or Port D Status Output Signal

These signals are used to report the direction setting (input or output) of p ort C or D to

external devices. Each of these signals is set to LOW resp ectively when port C or D is

assigned as an input p ort. It is set to HIGH respectively when p ort C or D is dened as an

output port. (Related HP-IB commands:

CIN,COUNT,DIN

, and

DOUT

.)

WRITE STROBE Output Signal

When data is output to any output p ort, a negative pulse is output to the WRITE STROBE

output. This negative output pulse noties an external device of data output to the parallel

I/O port. The pulse width is 10s(typical). Figure 7-6 shows the timing chart for the

WRITE STROBE output and data output.

Figure 7-6. Write Strobe Signal Timing Chart

INPUT1 Input Signal

When a negative pulse is input to INPUT1, OUTPUT1 and OUTPUT2 are set to LOW

or HIGH. The time interval is 200 ns (typical). An HP-IB command is used to determine

whether LOW or HIGH is to be set. The pulse width of the signal input to INPUT1 must be

1s or more. (Related HP-IB commands:

TRGOUT

WRITE STROBE Output for the PASS/FAIL Output

Outputs a negative pulse when a limit test result has been output through the PASS/FAIL

output line. The output signal informs an external device of the limit test result b eing output

through the PASS/FAIL output. The pulse width is 10s(typical).

SWEEP END Output

When the HP 4395A completes a measurement in the Tester mo de or a sweep in the Analyzer

mode, a negative pulse is output. When measurements are repeated with a continuous trigger,

the pulse is output at every measurementorsweep end. The pulse width is 20s(typical).
