Language Dictionary

Introduction

This section gives the syntax and parameters for all the IEEE 488.2 SCPI commands and the Common commands used by the dc source. It is assumed that you are familiar with the material in chapter 4, which explains the terms, symbols, and syntactical structures used here and gives an introduction to programming. You should also be familiar with chapter 5, in order to understand how the dc source functions.

The programming examples are simple applications of SCPI commands. Because the SCPI syntax remains the same for all programming languages, the examples given for each command are generic.

Syntax Forms

Syntax definitions use the long form, but only short form headers (or "keywords")

 

appear in the examples. Use the long form to help make your program self-

 

documenting.

Parameters

Most commands require a parameter and all queries will return a parameter. The

 

range for a parameter may vary according to the model of dc source. When this is the

 

case, refer to the Specifications table in Appendix A.

Related

Where appropriate, related commands or queries are included. These are listed

Commands

because they are either directly related by function, or because reading about them

 

will clarify or enhance your understanding of the original command or query.

Order of

The dictionary is organized according to the following functions: calibration, display,

Presentation

measurement, output, status, system, trigger, and common commands. Both the

 

subsystem commands and the common commands that follow are arranged in

 

alphabetical order under each heading.

Subsystem Commands

Subsystem commands are specific to functions. They can be a single command or a group of commands. The groups are comprised of commands that extend one or more levels below the root.

The subsystem command groups are arranged according to function: Calibration, Display, Measurement, Output, Status, System, and Trigger. Commands under each function are grouped alphabetically. Commands followed by a question mark (?) take only the query form. When commands take both the command and query form, this is noted in the syntax descriptions. Table 6-1 lists all of the subsystem commands in alphabetical order.

Common Commands

Common commands begin with an * and consist of three letters (command) or three letters and a ? (query). They are defined by the IEEE 488.2 standard to perform common interface functions. Table 6-2 lists all of the common commands in alphabetical order.

Programming Parameters

Table 6-3 lists all of the output programming parameters.
