6.2.4.2 Instrument-Control Commands
Instrument-control commands are based on a hierarchical structure and can be repre-
sented in a command tree. The command headers are built with one or several mne-
monics (keywords). The first level (root level) mnemonic identifies a complete command
system.
Example:
SOURce...
This mnemonic identifies the
SOURce
command system which provides
generator settings.
For commands of lower levels, the complete path must be specified, starting on the left
with the highest level, the individual keywords being separated by a colon ":".
Example:
SOURce:GPRF:GENerator:STATe ON
This command is located on the fourth level of the
SOURce
system. It turns on the RF
generator signal.
Below some rules are described that simplify / abbreviate the command syntax and help
to read the command reference sections.
Repeated mnemonics with different meaning
The same mnemonics may be used on different command levels, not necessarily with
the same meaning. The actual meaning of a mnemonic depends on its position in the
command header.
Example:
SOURce:GPRF:GENerator:RFSettings:FREQuency lGHZ
This command contains the mnemonic
SOURce
in the first command level ("define RF
generator settings"). The command defines the frequency of the GPRF generator signal.
CONFigure:GPRF:MEASurement:POWer:TRIGger:SOURce
This command contains the mnemonic
SOURce
in the sixth command level. It selects the
source of the trigger events for the GPRF Power measurement.
Special characters
●
| A vertical stroke in the parameter list characterizes alternative parameter settings.
Only one of the parameters separated by | must be selected.

ROUTe:GPRF:GENerator:SCENario:SALone RF1O | RF1C | RF2C
