In This Book
This book is your guide to programming the Infiniium-Series Oscilloscopes.
Chapters 1-5 give you an introduction to programming the oscilloscopes, along
with necessary conceptual information. These chapters describe basic program
communications, interface, syntax, data types, and status reporting.
Chapter 6 shows example BASIC and C programs, and describes chunks of one
program to show you some typical applications. The BASIC and C example
programs, and a "readme" file are also shipped on a disk with the oscilloscope.
Chapters 7-24 describe the commands used to program the Infiniium-Series
Oscilloscopes. Each chapter describes the set of commands that belong to an
individual subsystem, and explains the function of each command. These
chapters include:
Common HARDcopy
Root Level HISTogram
SYSTem MARKer
ACQuire MEASure
CALibration Mask TESt
CHANnel SELF-Test
DISK TIMe Base
DISPlay TRIGger
EXTernal Channel WAVeform
FUNCtion Waveform MEMory
Chapters 25 and 26 describe the language compatibility for 548xx,
Hewlett-Packard 547xx, and Hewlett-Packard 545xx Oscilloscopes. These
chapters also show you how to choose one of these command languages if you
want to use existing programs on Infiniium Oscilloscopes without having to
modify your programs.
Chapter 27 describes error messages.
Command syntax diagrams are in the Programmer's Quick Reference.
A Quick Start Guide, Online User's Guide, and Service Guide also ship with the
548xx oscilloscopes.

Introduction to Programming
Introduction to Programming
This chapter introduces the basics for remote programming of an
oscilloscope. The programming commands in this manual conform to
the IEEE 488.2 Standard Digital Interface for Programmable
Instrumentation. The programming commands provide the means of
remote control.
Basic operations that you can do with a computer and an oscilloscope
include:
