4.12 INSTRUMENT CONTROL COMMANDS
Instrument control commands are grouped into logical subsystems according to the SCPI
instrument model. The commands are comprised of mnemonics indicating the subsystem to
which the command belongs, and the hierarchy within that subsystem. When the command is
to be referred to the Root node, it should be prefixed with a colon (:). Mnemonics appearing in
square brackets [...] are optional. The '|' character is used to denote a choice of specifications.
The '<ws>' is used to denote a white space character.
4.12.1 SOURce Subsystem
The Source Subsystem controls the frequency, voltage and pulse characteristics. The command
structure is as follows:
:SOURce
:FREQuency
