Agilent E1351A/53A 16-Channel FET

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

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 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 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 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.
