[SENSe<1|2>:]SWEep:EGATe:TYPE LEVel | EDGE
This command sets the type of triggering (level or edge) by the external gate signal.
The gate opening time cannot be defined with the parameter EGATe:LENGth in case of level
triggering. The gate is closed when the gate signal disappears.
Example: "SWE:EGAT:TYPE EDGE"
Characteristics: *RST value: EDGE
SCPI: device-specific
Mode: A
[SENSe<1|2>:]SWEep:EGATe:POLarity POSitive | NEGative
This command determines the polarity of the external gate signal. The setting is valid both for the
edge of an edge-triggered signal and the level of a level-triggered signal.
Example: "SWE:EGAT:POL POS"
Characteristics: *RST value: POSitive
SCPI: device-specific
Mode: A
[SENSe<1|2>:]SWEep:EGATe:HOLDoff 125 ns to 100 s
This command defines the delay time between the external gate signal and the continuation of the
sweep.
Example: "SWE:EGAT:HOLD 100us"
Characteristics: *RST value: 0s
SCPI: device-specific
Mode: A
[SENSe<1|2>:]SWEep:EGATe:LENGth 0 to 100 s
In case of edge triggering, this command determines the time interval during which the instrument
sweeps.
Example: "SWE:EGAT:LENG 10ms"
Characteristics: *RST value: 0s
SCPI: device-specific
Mode: A
[SENSe<1|2>:]SWEep:EGATe:SOURce EXTernal | IFPower | RFPower
This command toggles between external gate signal and IF power signal as a signal source for the
gate mode. 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).
Note: Selection RFPower is only available with option R&S FSP-B6 (TV and RF Trigger).
Example: "SWE:EGAT:SOUR IFP" 'Switches the gate source to IF power.
Characteristics: *RST value: IFPower
SCPI: device-specific
Mode: A
