7.16.10 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.
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
