Putting Multiple Commands on the Same Line

Putting Multiple Commands on the Same Line

Multiple commands can be written on the same line, reducing your code space requirement. To do this:

•Commands must be separated with a semicolon (;).

•If the commands are in different subsystems, the key word for the new subsystem must be preceded by a colon (:).

•If the commands are in the same subsystem, the full hierarchy of the command key words need not be included. The second command can start at the same key word level as the command that was just executed.

SCPI Termination and Separator Syntax

A terminator must be provided when an instrument is controlled using RS-232 (Option 1AX). There are several issues to be understood about choosing the proper SCPI terminator and separator when this is the case. There is no current SCPI standard for RS-232. Although one intent of SCPI is to be interface independent, <END> is only defined for IEEE 488 operation. At the time of this writing, the RS-232 terminator issue was in the process of being addressed in IEEE standard 1174.

A semicolon (;) is not a SCPI terminator, it is a separator. The purpose of the separator is to queue multiple commands or queries in order to obtain multiple actions and/or responses. Make sure that you do not attempt to use the semicolon as a terminator when using RS-232 control.

Basically all binary trace and response data is terminated with <NL><END>, as defined in Section 8.5 of IEEE Standard 488.2-1992, IEEE Standard Codes, Formats, Protocols and Common Commands for Use with ANSI/IEEE Std 488.1-1987. New York, NY, 1992.

The following are some examples of good and bad commands. The examples are created from an EMC analyzer with the simple set of commands indicated below:

[:SENSe]

:POWer

[:RF] :ATTenuation 40dB

[:SENSe]

:FREQuency

:STARt

:POWer

[:RF]

:MIXer

:RANGe

[:UPPer]
