1-2 Introduction

How to Use the Program Modules

This manual provides many sample program modules that are not in a complete program

style.You can easily understand the module's objective because the program module does

not includes unnecessary code.You can use these modules to build your own program by

combining them.

The program modules are provided in the following style and typeface:

THIS IS A SAMPLE CODE.

As shown in the example above, a module has no line number, no initializing part, and no

END

statement. All these are required for an executable BASIC program.

Building a Working Program Using Program Modules

To make a program that uses sample program modules, perform the following steps:

1. Add an initializing module at the beginning of your program.

2. Arrange the program modules.

3. Add an

statement on the last line executed by your program.

ASIC editor.

Initializing Module

The initializing module denes a hardware identier as a variable to eliminate the dierence

between Instrument BASIC and HP BASIC. Usually, you can use the same program for

Instrument BASIC and HP BASIC by changing the initializing module. The initializing module

also intializes an HP-IB.

The following are the initializing modules for a program:

ASSIGN @Hp4291 TO 800

Scode=8

ABORT Scode

CLEAR @Hp4291

Assigning HP-IB address to 800.

Assigning interface select code to 8.

Get active control.

Preset the interface.

Module 1-1. Initialize Module for Instrument BASIC

ASSIGN @Hp4291 TO 717

Scode=7

ABORT Scode

CLEAR @Hp4291

Assigning HP-IB address to 717.

Assigning interface select code to 7.

Get active control.

Preset the interface.

Module 1-2. Initialize Module for the External Controller

Each module of this manual assumes that one of the initializing modules exists at the beginning

of the program, and uses the following variables without notice:

1-4 Introduction

HP-IB Overview

The HP-IB is a general purpose digital interface system that is used to integrate the controller,

measurement instruments, and peripherals into a system. HP-IB is Hewlett-Packard's

implementation of the IEEE 488 Bus.

Controller

The controller is a device that can address an HP-IB device to talk (output data) or listen

(receive data).

The active controller can control the other devices on the bus at that time (when multiple

controllers are connected). Only one controller can be active at a time. The active controller

can pass control to another controller by using the

Only one controller can be a system controller on the same bus. The system controller is

the active controller when the system is turned on. When another controller is the active

controller, the system controller can become the active controller at any time by executing

ABORT

select-code

PASS CONTROL

command.

Introduction 1-5

Device Selector

HP-IB device control is accomplished by sending commands from the active controller. The

active controller can select the target device for the commands by specifying the device

selector.

Figure 1-1. HP-IB Device and Address

Figure 1-1 shows the relationship between the HP-IB address and the device selector

example, the device selector of the printer on HP-IB with an address of \1," is \701" on the

HP-IB.

HP Instrument BASIC is connected in the HP 4291B internally by the internal interface. The

interface select code of the internal interface is \8" to distinguish it from the external select

code of \7."

You can use any address from \00" to \30" to specify the internally connected analyzer from

Instrument BASIC, because only the analyzer is connected on the internal interface

manual uses address \00," thus the device selector is \800."

1-6 Introduction

HP-IB Commands

The analyzer is equipped with the Hewlett-Packard Interface Bus (HP-IB) remote programming

digital interface. The HP-IB is Hewlett-Packard's hardware, software, documentation, and

support for the IEEE 488.1, IEC-625, IEEE 488.2, and JIS-C1901 worldwide standards for

interfacing instruments.

The HP-IB commands implemented in the HP 4291B are divided into the following three

categories: common commands, instrument control commands, and simple commands.

The HP 4291B's HP-IB commands conform to the Standard Commands for Programmable

Instruments (SCPI). SCPI is the new instrument command language for controlling instruments

that goes beyond IEEE 488.2 to address a variety of instrument functions in a standard

manner.

Common Commands

Common commands are dened by the IEEE 488.2 standard. All common commands begin

with an asterisk (3).

For example,

CLS

Instrument Control Commands

Instrument control commands are dened by SCPI, and include all measurement functions

and some general purpose functions. Instrument control commands consist of subsystems.

Each subsystem is a set of commands that roughly corresponds to a functional block inside the

instrument.

Instrument control commands have a hierarchical structure, called a

command tree,

that

consists of several nodes separated by colons.

For example,

CALCulate:EVALuate:BAND:FULL

Simple Commands

Simple commands are analyzer-specic commands that conform to IEEE 488.2. Each simple

command controls some measurement function that is normally programmed by sending

multiple instrument control commands.To reduce the number of program lines and make the

program simpler, these functions can also be executed by using a simple command instead of

the multiple instrument control commands.

Note

All HP-IB commands implemented the analyzer are listed in Chapter 11.

Introduction 1-7

Program Message Syntax

This section explains the construction of program messages.A

program message

is the

message that you send from a computer to an instrument. Program messages consist of

commands combined with appropriate punctuation and program message terminators.

Command Abbreviations

Many instrument control commands have a long and a short form. The short form is obtained

by deleting the lower case letters. The analyzer accepts both forms.

For example, the short form of

(The analyzer does

not

accept anything in between, such as

:INITiateis:INIT

and the long form of it is

:INITIA

:INITIATE

Some commands have a numerical sux. The numerical sux can be omitted, and the

analyzer recognizes that a numerical sux of1is implied in this command.

For example in

DISP:CMAP:COL

DISPlay:CMAP:COLor{1-14}

, it is recognized as

DISP:CMAP:COL1

, the numerical sux is

(the 1 is implied).

{1-14}

. If you send

Upper and Lower Cases

Letter cases (upper and lower) are ignored.

Program Message Terminator

A program message must end with the

program message terminators

Figure 1-2. Program Message Terminators

<^END>

means that End of Identify (EOI) is asserted on the HP-IB interface at the same time

the preceding data byte is sent.

The HP BASIC

OUTPUT

statement automatically sends program message terminators after the

last data byte.

1-8 Introduction

Multiple Messages

To send more than one command in the same message, you must separate them with a

semicolon(;):

SENS:FREQ:STAR 100MAHZ;STOP 1GHZ

For more information, see \Command Tree and Compound Header Usage", later in this chapter.

Query and Response Message Syntax

All commands can be queried except the commands described as \no query" in the command

reference.To send a query message, add?after the last command mnemonic.

SENS:FREQ:STAR?

A query response indicates the current setting of the analyzer. A response message may

contain both commas and semicolons as separators. When a single query command returns

multiple values, a comma is used to separate each data item. When multiple queries are sent

in the same message, the group of data items corresponding to each query are separated by

a semicolon. For example, the ctitious query

QUERY1?;QUERY2?

might return a response

message of:

After the message,

is always sent as a response message terminator.

Parameters

There must be a

example below) and the rst parameter (

between the last command mnemonic (

100MAHZ

, in the example below).

SOUR:FREQ

, in the

SOUR:FREQ 100MAHZ

If you send more than one parameter with a single command, each parameter must be

separated by a comma.

DATA AOFF,2

Each command reference contains information about the parameters available for the

individual commands. There are parameters that are spelled out (for example OFF, ON, \TR1")

or parameters shown as a word enclosed in

is a white space character (ASCII-encoded byte in the range of 00-09, 0B-20

, that represents some value.

(0-9, 11-32 decimal) ) or a series of the white space characters.

Variable Types

The variable parameters used in HP-IB commands are of three types:<numeric>,<string>,

and<block>.

numeric>represents numeric parameters as follows:

100

100.0

1.0E6

100.

1.23,+235

7.89e001

integer

xed decimal point

oating decimal point

fractional digits optional

leading signs allowed

use either E or e in exponentials

digits to the left of the decimal point are optional

Introduction 1-9

The analyzer accepts<numeric>parameters in various formats and responds to a particular

query in a predened and xed format.

The analyzer setting programmed with a numeric parameter can assume a nite number of

values, so the analyzer automatically rounds o the parameter.For example, if you specied

the OSC level as

The<numeric>whose absolute value is less than 1000000 is returned in the xed decimal point format (If

501MV

, it would be rounded o to

500MV

the value is integer, the return format is integer).

The<numeric>whose absolute value is, or more than 1000000 is returned in the oating decimal point

format.

Sux

When a command has a specied sux, the sux multiplier and sux units can be used

with parameters as follows (the sux multiplier must be used with the sux unit):

Parameter Sux Unit Available Multipliers

)

Resistance and reactance are the same

Conductance or susceptance are the same

The sux is optional and can be omitted. If you omit it, the analyzer assumes that the

default sux is sent.

string>is a string parameter that contains ASCII characters. A string must begin with a

double quote (ASCII 34 decimal) and end with a double quotation mark. You can include the

quotation mark as part of the string by typing it twice without any characters in between

the quotation marks.Or, you can avoid typing the quotation marks twice by using a single

quotation mark (ASCII 39 decimal).

Example of<string>TITLE

OUTPUT @Meter;"DISP:TEXT10 'TITLE'"

OUTPUT @Meter;"DISP:TEXT10 ""TITLE"""

The quote to mark the beginning and end of the string is called the

using single quote
