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 Mode.

Remote command:

[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:RETRace on page 354

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 Spacing 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] on page 356

"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

on page 357

Dwell Time - LF Sweep

Defines the duration of the individual sweep steps.
