frequency sweep, FFT sweep, zero span and I/Q mode measurements using an IF
Power trigger.
Parameters:
<DelayTime> Range: 0 s to 30 s
*RST: 0 s
Example:
SWE:EGAT:HOLD 100us
Manual operation: See "Gate Delay" on page 433
[SENSe:]SWEep:EGATe:LENGth <GateLength>
This command defines the gate length.
Parameters:
<GateLength> Range: 125 ns to 30 s
*RST: 400μs
Example:
SWE:EGAT:LENG 10ms
Manual operation: See "Gate Length" on page 434
[SENSe:]SWEep:EGATe:POLarity <Polarity>
This command selects the polarity of an external gate signal.
The setting applies both to the edge of an edge-triggered signal and the level of a
level-triggered signal.
Parameters:
<Polarity> POSitive | NEGative
*RST: POSitive
Example:
SWE:EGAT:POL POS
Manual operation: See "Slope" on page 432
[SENSe:]SWEep:EGATe:SOURce <Source>
This command selects the signal source for gated measurements.
If an IF power signal is used, the gate is opened as soon as a signal at > -20 dBm is
detected within the IF path bandwidth (10 MHz).
For more information see "Trigger Source" on page 427.
Parameters:
<Source> EXTernal | EXT2 | EXT3 | IFPower | IQPower | VIDeo |
RFPower | PSEN
*RST: IFPower
Example:
SWE:EGAT:SOUR IFP
Switches the gate source to IF power.
