Command Reference
Using This Chapter
This chapter describes Standard Commands for Programmable Instruments
(SCPI) and summarizes IEEE 488.2 Common (*) commands applicable to
both RF Multiplexer modules. See the appropriate HP B-size or C-size
configuration guide for additional information on SCPI and Common
commands. This chapter contains the following sections.

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 shown be
l
ow:
*RST *ESR 32 *STB?
SCPI Command
Format
SCPI commands perform functions like closing switches, and 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 commands, and their parameters. The following
example shows part of a typical subsystem:
[ROUTe:]
CLOSe< channel_list >
SCAN< channel_list >
:MODE?
[ROUTe:] is the root command, CLOSe and SCAN are second-level
commands with parameters, and :MODE? is a third-level command.
