Trigger Offset
Defines the time offset between the trigger event and the start of the sweep.
For more information, see Chapter 10.10.1.1, "Trigger Offset" , on page 183.
"values > 0" Measurement starts after the trigger event has occurred.
"values < 0" Measurement starts before the trigger event occurs (pretrigger).
The maximum allowed range is limited by the measurement time.
Pretriggering is possible in the time domain.
Remote command:
TRIGger<tp>[:SEQuence]:HOLDoff[:TIME]
on page 515
Trigger Slope
Selects the polarity of the trigger source.
The trigger slope is unavailable for the free run trigger.
"Rising" The measurement starts when the signal rises to the trigger level.
"Falling" The measurement starts when the signal falls down to the trigger
level.
Remote command:
TRIGger<tp>[:SEQuence]:SLOPe
on page 516
Gated Trigger
Switches gated triggering on or off.
Note: Gating is not available for measurements on I/Q based data.
Remote command:
[SENSe:]SWEep:EGATe
on page 514
Gate Mode
Sets the gate mode.
For more information see Chapter 10.10.1.2, "Gated Measurements" , on page 183
"Edge" The trigger event for the gate to open is the detection of the signal
edge.
After the gate signal has been detected, the gate remains open until
the gate length is over.
"Level" The trigger event for the gate to open is a particular power level.
After the gate signal has been detected, the gate remains open until
the signal disappears.
Remote command:
[SENSe:]SWEep:EGATe:TYPE
on page 515
Gate Delay
Defines the delay time between the gate signal and the continuation of the measure-
ment.
In the Spectrum application, the delay position on the time axis in relation to the mea-
surement is indicated by a line labeled "GD".
For more information see Chapter 10.10.1.2, "Gated Measurements" , on page 183
