SOFTKEYS
Boldface type is used when a term is dened. For example:
icons
are
symbols.
Italic type is used for emphasis and for titles of manuals and other
publications.
Italic type is also used for keyboard entries when a name or a variable
must be typed in place of the words in italics.For example:
lename
type the name of a le such as
means to type the word

How to Use This Manual
This guide will help you learn how to eectively use HP Instrument BASIC (IBASIC) of the
HP 4352B VCO/PLL Signal Analyzer. It will help you to perform typical operations involving
program creation, editing, and execution. It will also show you how to save and recall
programs, and how to make the best use of the HP Instrument BASIC's front-panel and
keyboard interface. Here is a brief guide to help you locate the necessary information in this
manual.
Chapter 2 introduces the analyzer's HP Instrument BASIC system and describes how to
connect and use a keyboard.
Chapter 3 and Chapter 4 show creating, getting, and saving programs to teach you front
panel and keyboard operation.
Chapter 5 introduces you to the editing environment.
Chapter 6 describes interfacing features for graphics, external connector to trigger
RUN/CONTinue of a program, and I/O port.
Chapter 7 introduces special features for auto loading a program, and the On Key Label
function (softkeys dened in a program). This chapter also describes techniques for speeding
up your programs.
Chapter 8 summarizes the unique features specied for the analyzer
Appendix A contains the information required to adept this manual to earlier versions or
congurations of the analyzer than the current printing date of this manual.
Appendix B provides references for BASIC commands specic to the analyzer's HP
Instrument BASIC.
Appendix C provides a handy reference guide to the analyzer's HP Instrument B
denitions for the mini-DIN keyboard.

Introduction to the System 2-1
Figure 2-1. Conguration Example of the HP Instrument B
The HP Instrument BASIC's programming interface includes an editor and a set of programming
utilities. The utilities allow you to perform disk I/O
your program.
The HP Instrument BASIC command set is similar to the command set of HP 9000 Series
200/300 BASIC. Therefore, HP Instrument BASIC programs can be run on any HP B
workstation with few if any changes.Porting information can be found in the

Setting the Size of Memory Area for HP Instrument BASIC
The size of the memory areas for the RAM disk memory and the variable of HP Instrument
BASIC (excluding common variables) can be changed according to your application.
Caution
When the memory partition is recongured, the analyzer goes to the initial
settings. That is, the RAM disk memory is initialized and all the data saved in
the RAM disk memory is destroyed, and the program on the BASIC editor is
destroyed.

Controlling the Analyzer
HP Instrument BASIC can control the analyzer (itself) through the \internal" HP-IB bus. This
means that an analyzer with HP Instrument BASIC includes both a controller and an analyzer
in the same instrument. They are connected through an internal HP-IB bus.
Note
The select code of the internal HP-IB interface is 8, and the HP-IB address of
the analyzer can be any number from 0 to 30. In this manual, we use \800" for
the device selector of the analyzer.
For more information on HP-IB addresses and device selectors, see \Device
Selectors" in the
Instrument BASIC Users Handbook
HP Instrument BASIC Interfacing Techniques
and \Available I/O Interfaces and Select
of the
HP
Codes" in Chapter 8.
