SCPI Command Reference
This chapter describes the Standard Commands for Programmable Instruments
(SCPI) command set and the IEEE-488.2 Common Commands for the HP E2270,
E2271, and E2272 Switch M-Modules. This chapter contains the following sections:

Commands are separated into two types: IEEE 488.2 Common commands and SCPI
commands.
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 (
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
The SCPI commands perform functions like closing switches, making
measurements, 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:]
<channel_list>
CLOSe
]is the root command,
[ROUTe:
A colon (
) always separates one command from the next lower-level command as
:
shown below:
[ROUTe:]OPEN?
The command syntax shows most commands as a mixture of upper- and lowercase
letters. The uppercase letters indicate the abbreviated spelling for the command. For
