Multiplexer Command Reference
This chapter describes Standard Commands for Programmable Instruments
(SCPI) commands and summarizes IEEE 488.2 Common (*) Commands
applicable to the 16-Channel FET and 16-Channel Thermocouple FET
Multiplexer 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 three or four 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
The SCPI commands perf orm 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 <
SCAN <
:MODE VOLT
[ROUTe:]
is the root command,
commands with <channel_list> as a parameter, and
