standard.
Instrument responses
Instrument responses (response messages and service requests) are messages which
the instrument sends to the controller after a query. They can contain measurement
results, instrument settings and information on the instrument status.
A.1.2 SCPI command structure
SCPI commands consist of a so-called header and, usually, one or more parameters.
The header and the parameters are separated by a whitespace. The headers can con-
sist of several mnemonics (keywords). Queries are formed by appending a question
mark directly to the header. The commands can be either device-specific or device-
independent (common commands). Common and device-specific commands differ in
their syntax.
Syntax for common commands
Common (= device-independent) commands consist of a header preceded by an aster-
isk (*) and possibly one or more parameters.

uppercase letters, the long form corresponds to the complete word. You can enter
either the short form or the long form; other abbreviations are not permitted.
