Retrace - LF Frequency Sweep
Activates that the signal changes to the start frequency value while it is waiting for the
next trigger event.
You can enable this feature, when you are working with sawtooth shapes in sweep
mode "Single" or "External Single", see
Remote command:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:RETRace
Step Lin/Log - LF Sweep
Sets the step width for the individual frequency sweep steps.
At each step this value is added to the current frequency.
Depending on the
mode you have set, the corresponding parameter is dis-
played.
"Step Lin"
The step width is a constant value in Hz.
Remote command:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP[:LINear]
"Step Log"
The step width is determined logarithmically in %, that means as a
constant fraction of the current frequency.
Remote command:
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic
Dwell Time - LF Sweep
Defines the duration of the individual sweep steps.
