Infiniium Oscilloscopes Programming Command Set ii iii iv v 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. vii viii Contents 1 Introduction to Programming Communicating with the Oscilloscope 1-3 Output Command 1-4 Device Address 1-4 Instructions 1-4 Instruction Header 1-4 White Space (Separator) 1-5 Braces 1-5 Ellipsis 1-5 Square Brackets 1-5 Program Data 1-5 Header Types 1-6 Duplicate Mnemonics 1-8 Query Headers 1-9 Program Header Options 1-10 Character Program Data 1-10 Numeric Program Data 1-11 Embedded Strings 1-12 Program Message Terminator 1-12 Common Commands within a Subsystem 1-13 Selecting Multiple Subsystems 1-13 Programming Getting Started 1-13 Initialization 1-14 Example Program using HP Basic 1-15 Using the DIGITIZE Command 1-16 Receiving Information from the Oscilloscope 1-18 String Variable Example 1-19 Numeric Variable Example 1-19 Definite-Length Block Response Data 1-20 Multiple Queries 1-21 Oscilloscope Status 1-21 2 LAN and GPIB I
