: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
[SOURce]:FREQuency:MODE?
This command sets the frequency mode of the signal generator to CW or swept. FIX |
CW Stops a frequency sweep
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.
:FREQuency:STARt [SOURce]:FREQuency:STARt
<value><unit> [SOURce]:FREQuency:STARt?
This command sets the first frequency point in a step sweep.
*RST The preset value is 1 GHz. Please refer to the Data Sheet. Range
Please refer to the Data Sheet.
:FREQuency:STOP [SOURce]:FREQuency:STOP
<value><unit> [SOURce]:FREQuency:STOP?
This command sets the last frequency point in a step sweep.
*RST The preset value is 2 GHz.
Range Please refer to the Data Sheet.
[SOURce]:FREQuency:STEP
[SOURce]:FREQuency:STEP[:LINear] <value><unit>
This command sets the step size for a linear step sweep.
[SOURce]:FREQuency:STEP:LOGarithmic
