Introduction
This instrument complies with the rules and conventions of the present SCPI version (see
SYSTem:VERSion? ).
SCPI (Standard Commands for Programmable Instruments) is an ASCII-based instrument command
language designed for test and measurement instruments. SCPI has two types of commands,
common and subsystem.
IEEE-488.2 Common Commands
The IEEE-488.2 standard defines a set of common commands that perform functions such as reset,
self-test, and status operations. Common commands always begin with an asterisk ( * ), are three
characters in length, and may include one or more parameters. The command keyword is separated
from the first parameter by a blank space. Use a semicolon ( ; ) to separate multiple commands as
shown below:
Subsystem Commands
Subsystem commands perform specific instrument functions. They are comprised of alphabetically
arranged commands that extend one or more levels below the root in a hierarchical structure, also
known as a
tree system . In this structure, associated commands are grouped together under a
common node or root, thus forming subsystems . A portion of the OUTPut subsystem is shown below
to illustrate the tree system. Note that some [optional] commands have been included for clarity.
OUTPut
[:STATe] OFF|0|ON|1
:DELay
:FALL <value>|MIN|MAX
:RISE <value>|MIN|MAX
:INHibit
:MODE LATChing|LIVE|OFF
