3 Keysight E1459A SCPI Command
Reference
The Standard Commands for Programmable Instruments (SCPI) commands
described in this chapter are only available in the downloadable SCPI driver for
the Keysight Command Modules such as the Keysight E1406. If you are not using
a command module, you should use the Keysight VXIplug&play driver. This driver
is available on the Keysight Instrument Drivers CD and available on the World
Wide Web.

Common Command Format

The IEEE 488.2 standard defines the Common commands that perform functions
like reset, self-test, status byte query, etc. Common commands are four or five
characters in length, always begin with the asterisk character (*), and may
include one or more parameters. The command keyword is separated from the
first parameter by a space character. Some examples of common commands are
shown below:
*RST *ESR 32*STB?

SCPI Command Format

The SCPI commands perform functions such as making measurements, querying
instrument states, or retrieving data. A command subsystem structure is a
hierarchical structure that usually consists of a top level (or root) command, one
or more low-level commands, and their parameters. The following example
shows the root command DISPlay and some of its lower-level subsystem
commands:
:DISPlay
:DISPlay is the root command, :MONitor is a second level commands, and
:PORT, PORT?, [:STATe], and [:STATe]? are third level commands.
:MONitor
:PORT <port>
:PORT? [MINimum | MAXimum | DEFault]
[:STATe] <state>
[:STATe]?
