Using This Chapter
This chapter describes Standard Commands for Programmable Instruments
(SCPI) commands and summarizes IEEE 488.2 Common (*) commands
applicable to the RF Multiplexer. See the
Agilent Command Module User’s
Guide
for additional information on SCPI and common commands.

Command Types
Commands are separated into two types: IEEE 488.2 Common Commands
and SCPI Commands.
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:
*RST
*ESR 32
*STB?
SCPI Command
Format
The SCPI commands perform functions like closing switches, querying
instrument states, or retrieving data. A subsystem command structure is a
hierarchical structure that usually consists of a top level (or root) command,
one or more lower level sub commands, and their parameters. The following
example shows a typical subsystem:
[ROUTe:]
CLOSe
<channel_list>
[ROUTe:] is the root command, :CLOSe is the second level sub command,
and
<channel_list>
is a parameter.
