:FREQuency[:CW]
[SOURce]:FREQuency[:CW] <value><unit>
[SOURce]:FREQuency[:CW]?
This command sets the signal generator output frequency for the CW frequency mode.
*RST 100 MHz
Range Please refer to the Data Sheet.
:FREQuency:MODE
[SOURce]:FREQuency:MODE FIX|CW|SWEep|LIST|CHIRp
[SOURce]:FREQuency:MODE?
This command sets the frequency mode of the signal generator to CW, (list) sweep or chirp.
FIX | CW Stops a frequency sweep or chirp.
SWEep or LIST This choice selects the swept frequency mode. If sweep triggering is set to
immediate along with continuous sweep mode, executing the command starts
the LIST or SWEep frequency sweep. In SWEep mode, frequency will be
determined by programmed values for the :STARt and :STOP :FREQuency
subsystem commands. In LIST mode, frequency is determined by
programmed values for :LIST:FREQuency.
CHIRp This choice selects the chirp mode. A chirp is a quasi-analog sweep over
limited bandwidth. Refer to the [SOURce]:CHIRp subsystem for
configuration.
:FREQuency:STARt
[SOURce]:FREQuency:STARt <value><unit>
[SOURce]:FREQuency:STARt?
This command sets the first frequency point in a chirp or step sweep.
*RST The preset value is 1 GHz. Please refer to the Data Sheet.
Range Please refer to the Data Sheet.
