[SENSe:]SWEep:EGATe <State>
This command turns gated measurements on and off.
In case of measurements with an external gate, the measured values are recorded as
long as the gate is opened. During a sweep the gate can be opened and closed sev-
eral times. The synchronization mechanisms with *OPC, *OPC? and *WAI remain
completely unaffected.
The measurement ends when a particular number of measurement points has been
recorded (see [SENSe:]SWEep:POINts on page 655).
Performing gated measurements turns the squelch off.
Parameters:
<State> ON | OFF | 1 | 0
*RST: 0
Example:
SWE:EGAT ON
Switches on the external gate mode.
SWE:EGAT:TYPE EDGE
Switches on the edge-triggered mode.
SWE:EGAT:HOLD 100US
Sets the gate delay to 100 µs.
SWE:EGAT:LEN 500US
Sets the gate opening time to 500 µs.
INIT;*WAI
Starts a sweep and waits for its end.
[SENSe:]SWEep:EGATe:HOLDoff <DelayTime>
This command defines the delay time between the gate signal and the continuation of
the measurement.
Note: If you perform gated measurements in combination with the IF Power trigger, the
R&S FPL1000 ignores the holding time for frequency sweep, FFT sweep, zero span
and I/Q mode measurements.
Parameters:
<DelayTime> Range: 0 s to 30 s
*RST: 0 s
Example:
SWE:EGAT:HOLD 100us
Manual operation: See " Gate Delay " on page 417
[SENSe:]SWEep:EGATe:LENGth <GateLength>
This command defines the gate length.
