SOURce:SWEep Subsystem

The SOURce: subsystem contains the commands for configuring RF sweep signals.

  • The keyword [:FREQuency] can be ommitted, then the commands are SCPI-compliant.
  • To activate a RF sweep mode, use the following commands:
    RF frequency sweep: SOURce:FREQuency:MODE SWEep (SOURce:FREQuency:MODE CW (off))
    RF level sweep: SOURce:POWer:MODE SWEep (SOURce:POWer:MODE CW (off))
  • All sweeps, including the LF sweep, can be set independently from each other.

This example shows how to set up a frequency sweep.

  1. Set the sweep range.

    [SOURce:]FREQuency:CENTer 200 MHz

    [SOURce:]FREQuency:SPAN 300 MHz

  2. Select linear or logarithmic spacing.

    [SOURce:]SWEep[:FREQuency]:SPACing LIN

  3. Set the step width and dwell time.

    [SOURce:]SWEep[:FREQuency]:STEP:LINear 20 MHz

    [SOURce:]SWEep[:FREQuency]:DWELl 12 ms

  4. Select the trigger mode.

    TRIGger:]FSWeep:SOURce SINGle

  5. Select the sweep mode and activate the sweep.

    [SOURce:]SWEep[:FREQuency]:MODE AUTO

    [SOURce:]FREQuency:MODE SWEep

  6. Trigger the sweep.

    [SOURce:]SWEep[:FREQuency]:EXECute

It is recommended that you switch off the "Start/Stop Display Update" for optimum sweep performance, especially with short dwell times (SYSTem:DISPlay:UPDate OFF).
