Typeface Conventions

Bold

Boldface type is used when aterm is dened. F

or example:

icons

are

symbols

Italics

Italic type is used for emphasis and for titles of manuals and other

publications

Italic type is also used for keyboard entries when aname or a variable

must be typed in place of the words in italics

.For example:

copy

lename

means to type the word

copy

,to

type a space, and then to

type the name of ale such as

file1

Computer

Computer font is used for on-screen prompts and messages.

HARDKEYS

Labeled keys on the instrument front panel are enclosed in

NNNNNNNNNNNNNNNNNNNNNNNNNN

SOFTKEYS

Softkeys located to the right of the CRT are enclosed in

NNNNN

Graphic Symbols

General denitions of other graphic symbols used in manuals.

COMPUTER

denotes information for aprogrammer using an external

computer as the system controller

ASIC

denotes information for aprogrammer using an analyzer with

Instrument B

ASIC as the system controller

How to Use This Manual

This manual provides an introduction to writing B

ASIC programs for the 4396B

Network/Spectrum Analyzer (analyzer). T

o 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

ou 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 locate these examples

Also

,depending upon your experience in writing BASIC programs using GPIB commands

,you

may want to do one of the following:

1. If you are an experienced programmer and have programmed GPIB systems before

,you can

scan the examples in this guide to nd out how the analyzer can be used in your system.

If you have never programmed an instrument similar to the analyzer

,you can start at the

beginning and do the examples that apply to your application.

2. If you are an experienced programmer, but do not have any knowledge of GPIB commands

review some examples to decide where you need help

.See the

GPIB Command R

eference

for additional information on GPIB commands.

3. If you are not an experienced programmer and you do not have any knowledge of GPIB

commands

,see the

GPIB Command R

eference

for alist of the documentation that you will

need to review before using this guide

The analyzer can also use Instrument B

ASIC. Documentation for Instrument B

ASIC and the

other manuals available for the analyzer is listed in the Documentation Map on the next page

ASIC program to control the

analyzer and describes how Instrument BASIC works with the analyzer

GPIB Command Reference (Agilent P

art Number 04396-900x4

)

The GPIB Command Reference provides a summary of all available GPIB commands

.It

also provides information on the status reporting structure and the trigger system (these

features conform to the SCPI standard).

Option 010 Operating Handbook (Agilent P

art Number 04396-900x6

)

The option 010 Operation Handbook describes the unique impedance measurement

functions of the 4396B with option 010.

Instrument B
