5.2.4.1 Common Commands
Common (=device-independent) commands consist of a header preceded by an
asterisk "*" and possibly one or more parameters.
Examples:
*RST RESET, resets the instrument.
*ESE 253
*IDN? IDENTIFICATION QUERY, queries the instrument identification
string.
5.2.4.2 Instrument-Control Commands
Instrument-control commands are based on a hierarchical structure and can be
represented in a command tree. The command headers are built with one or several
mnemonics (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<i>:STATe ON
This command is located on the fourth level of the SOURce system. It turns on the
RF generator signal. The numeric suffix denotes a particular instance of the RF
generator; see General Command Structure.
The following rules simplify and abbreviate the command syntax:
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<i>: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<i>: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.
Optional mnemonics
Commands may contain optional mnemonics. These mnemonics are marked by
