Using This Chapter
This chapter describes Standard Commands for Programmable Instruments
(SCPI) commands and summarizes IEEE 488.2 Common (*) Commands
applicable to the Microwave Switch. See the HP 75000 Series B
Mainframe HP E1300A/E1301A User’s Manual or the HP 75000 Series C
HP E1406 User’s Manual 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 sh`own below:
*RST
*ESR 32
*STB?
SCPI Command
Format
SCPI commands perform functions like closing switches, making
measurements, 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.
