SOURce:LFOutput Subsystem

The SOURce:LFOutput subsystem contains the commands for setting the LF signal source in CW and Sweep mode and for analog modulation.

An LF generator is always available in the instrument. A second LF generator is optional.

The suffix for LFOutput<ch> denotes the selected LF generator. The source for the LF sweep (LF generator 1 or 2) is selected with command SOURce:LFOutput:SWEep:FREQuency:SOURce.

Example

The following example shows how to set an LF sweep.

  1. Set the sweep range.

    LFOutput:FREQuency:STARt 4 kHz

    LFOutput:FREQuency:STOP 10 kHz

  2. Select linear or logarithmic sweep spacing.

    LFOutput:SWEep[:FREQuency]:SPACing LIN

  3. Set the step width and dwell time.

    LFOutput:SWEep[:FREQuency]:STEP[:LINear] 100 Hz

    LFOutput:SWEep[:FREQuency]:DWELl 20 ms

  4. Determine the sweep mode.

    LFOutput:SWEep:MODE AUTO

  5. Determine the trigger.

    TRIGger0:SOURce SINGle

  6. Activate the sweep.

    LFOutput:FREQuency:MODE SWEep

  7. Trigger the sweep (depending on the mode).

    LFOutput:SWEep:EXECute
