8000A Series Infiniium

Oscilloscopes

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 are also shipped on a disk with the oscilloscope.

Chapters 7-25 describe the commands used to program the Infiniium

Oscilloscopes. Each chapter describes the set of commands that belong to an

individual subsystem, and explains the function of each command. These

chapters include:

Error Messages chapter describes error messages.
