Command Types

Commands are separated into two types: IEEE 488.2 Common Commands and SCPI Commands.

Common Commands Format

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: *RST *ESR 32 *STB?

SCPI Command Format The SCPI commands perform functions such as making measurements, querying instrument states, or retrieving data. The SCPI commands are grouped into command "subsystem structures". A command subsystem structure is a hierarchical structure that usually consists of a top level (or root) command, one or more low-level commands, and their parameters. The following example shows the root command CALibration and its lower-level subsystem commands:

CALCulate :LIMit:FAIL?

:LIMit:LOWer[:STATe] ON 1 OFF 0 :LIMit:LOWer[:STATe]? :LIMit:LOWer:DATA < value> :LIMit:LOWer:DATA? :LIMit:UPPer[:STATe] ON 1 OFF 0 :LIMit:UPPer[:STATe]? :LIMit:UPPer:DATA <value> :LIMit:UPPer:DATA?
