HP E1366A/E1367A RF Multiplexers Command Reference

Using This Chapter

This chapter describes Standard Commands for Programmable Instruments (SCPI) and summarizes IEEE 488.2 Common (*) commands applicable to both RF Multiplexer modules. See the appropriate HP B-size or C-size configuration guide for additional information on SCPI and Common commands. 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 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 shown be ow:

*RST *ESR 32 *STB?

SCPI Command Format

SCPI commands perform functions like closing switches, 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:]

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.
