Multiplexer Command Reference

Using This Chapter

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:

Command Types

Common Command Format

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

*ESR 32

*STB?

SCPI Command Format

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 <channel_list>

SCAN <channel_list>

:MODE VOLT

[ROUTe:] is the root command, CLOSe and SCAN are second-level commands with <channel_list> as a parameter, and MODE is a third-level command with the parameter VOLT.
