Chapter 6 SCPI Command Reference

This chapter provides descriptions of all available remote communication commands which correspond

to Standard Commands for Programmable Instruments (SCPI) command sets. Use this chapter as a

reference.

6.1 Command structure

Commands are divided into two types: common commands and SCPI commands. The common

commands are defined in IEEE std. 488.2-1987, and these commands are common for all devices. Not

all commands are supported by the multimeter. The SCPI commands are used to control all of the
meter’s functions. They are tree structured with three levels of depth. (The highest level commands are
called the subsystem commands in this manual.) So the lower level commands are legal only when the

subsystem commands have been selected. A colon (:) is used to separate the higher level commands

and the lower level commands. See Figure 6-1 as an example.

6.2 Command Syntax

The information in this section covers the syntax for both common commands and SCPI commands.

6.2.1 Commands and command parameters

Common commands and SCPI commands may or may not require specifying a parameter. The

following are some examples:

*RST No parameter used

:FORMat Parameter required

:IMMediate No parameter used

Commands that require a parameter input must have a space in between the command and the

parameter.
