Command Reference

This chapter describes the following for Agilent E5250A:

•SCPI commands available to control the E5250A via GPIB interface.

SCPI is a universal programming language for electronic test and measurement instruments, and is based on IEEE 488.1 and IEEE 488.2.

SCPI commands are divided into two types: common commands and subsystem commands.

Common commands are generally not measurement related, but are used to manage status registers, data storage, and so on. Common commands are defined by IEEE 488.2. All common commands begin with an asterisk, such as *RST.

Subsystem commands are mostly measurement related and some are general purpose. Subsystem commands have a hierarchical structure that uses a colon between mnemonics (keywords), such as :DIAG:TEST:CARD:RES.

Commands for the following subsystems are available for the E5250A:

DIAGnostic commands for performing self-test.

ROUTe	commands for signal routing.
SYSTem	commands for controlling other functions that are not related
	to instrument performance.

Commands are listed in alphabetical order in this chapter.

•Status reporting structure

These are IEEE 488.2 status structures (registers), which can be set or read by the common commands.

For SCPI programming to control the E5250A, refer to Chapter 6, “Programming the E5250A.”

For a quick reference list of all SCPI subsystem commands described in this chapter, refer to Chapter 12, “SCPI Command Summary.”

For error messages related to the SCPI commands, refer to Chapter 11, “Error Messages.”.
