Language Dictionary

This section gives the syntax and parameters for all the IEEE 488.2 SCPI commands and the Common commands used by

the power supply. It is assumed that you are familiar with the material in "Chapter 2 - Remote Programming". That chapter

explains the terms, symbols, and syntactical structures used here and gives an introduction to programming. You should

also be familiar with "Chapter 5 - Front Panel Operation" (in the Operating Guide) in order to understand how the power

supply functions.

The programming examples are simple applications of SCPI commands. Since SCPI syntax remains the same for all

programming languages, the examples are generic.

Syntax definitions use the long form, but only short form headers (or "keywords") appear in the examples. If you have any

concern that the meaning of a header in your program listing will not be obvious at some later time, then use the long form

to help make your program self-documenting.

Most commands require a parameter and all queries will return a parameter. The range for a parameter may vary according

to the model of power supply. Parameters for all current models are listed in Table 3-1 at the end of this chapter.

Where appropriate, related commands or queries are included. These are listed either because they are directly related by

function or because reading about them will clarify or enhance your understanding of the original command or query.

The dictionary is organized as follows:

• IEEE 488.2 common commands, in alphabetical order.

• Subsystem command s.

Common commands begin with an * and consist of three letters (command) or three letters and a ? (query). Common

commands are defined by the IEEE 488.2 standard to perform some common interface functions. The power supply

responds to the 13 required common commands that control status reporting, synchronization, and internal operations. The

power supply also responds to five optional common commands controlling triggers, power-on conditions, and stored

operating parameters.

Subsystem commands are specific to power supply 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 description of subsystem commands

follows the listing of the common commands.
