[SENSe:]SWEep:EGATe <State>
This command switches on/off the sweep control by an external gate signal. If the
external gate is selected the trigger source is automatically switched to EXTernal as
well.
In case of measurement with external gate, the measured values are recorded as long
as the gate is opened. During a sweep the gate can be opened and closed several
times. The synchronization mechanisms with *OPC, *OPC? and *WAI remain com-
pletely unaffected.
The sweep end is detected when the required number of measurement points (691 in
"Spectrum" mode) has been recorded.
Parameters:
<State> ON | OFF
*RST: OFF
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.
Manual operation: See "Gated Trigger (On/Off)" on page 320
See "Gate Ranges" on page 320
See "Gated Trigger" on page 378
[SENSe:]SWEep:EGATe:HOLDoff <DelayTime>
This command defines the delay time between the external gate signal and the contin-
uation of the sweep.
Note: Using gate mode "level" (see [SENSe:]SWEep:EGATe:TYPE on page 843)
and an IFP trigger (see TRIGger<n>[:SEQuence]:SOURce on page 839), the hold-
off time for the IFP trigger is ignored for frequency sweep, FFT sweep, zero span and
IQ mode measurements.
Parameters:
<DelayTime> 0 s to 30 s
*RST: 0s
Example:
SWE:EGAT:HOLD 100us
