Command Syntax
Common Command
Format
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:
*IDN? *CLS *OPC?
Standard Command
Format
Standard commands perform functions such as making measurements,
querying instrument states, or retrieving data. A command subsystem is a
hierarchical structure that usually has a top level (or root) command, one or
more low-level commands, and their parameters. This is an example of a
typical subsystem:
RUNTime
:SOURce
:SOURCE1
:TRIGger
RUNTime
is the root command, SOURce is a second level command, SOURCE1
is a third level command, and TRIGGER is a fourth level command.
A colon (:) always separates a command from the next lower level
command, as shown below:
