FSV-K91/91n/91ac/91p
201Operating Manual 1176.7649.02 ─ 04
Usage: SCPI confirmed
Mode: WLAN
Manual operation: See "Sweep Count " on page 90
[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.
[SENSe:]SWEep:EGATe:HOLDoff[:TIME] <Time>
This command defines the gate delay in the capture buffer in time units. The range of
this value is dependent on the last run measurement.
Parameters:
<Time> *RST: 100μs
Example:
SWE:EGAT:HOLD 125us
Sets a delay of 125μs in the capture buffer.
Mode: WLAN
[SENSe:]SWEep:EGATe:HOLDoff:SAMPle <NumberSamples>
This command defines the gate delay in the capture buffer as a number of samples.
The range of this value is dependent on the last run measurement.
