"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.
Note: If you perform gated measurements in combination with the IF
Power trigger, the R&S FSW ignores the holding time for frequency
sweep, FFT sweep, zero span and I/Q mode measurements.
This mode is not supported when using R&S Power Sensors as
power triggers ("Trg/Gate Source" = Power Sensor or External).

Gate Delay
Defines the delay time between the gate signal and the continuation of the measure-
ment.
The delay position on the time axis in relation to the sweep is indicated by a line
labeled "GD".
For more information see Chapter 8.6.2.1, "Gated Measurements", on page 488
Remote command:
[SENSe:]SWEep:EGATe:HOLDoff on page 1058
Gate Length
Defines how long the gate is open when it is triggered.
The gate length can only be set in the edge-triggered gate mode. In the level-triggered
mode the gate length depends on the level of the gate signal.
The gate length in relation to the sweep is indicated by a line labeled "GL".

8.6.2.3 Continuous Gate Settings
Access: "Overview" > "Trigger" > "Trigger / Gate Config." > "Cont. Gate" tab
Continuous gating allows you to perform a continuous gated sweep after a single
external trigger is received.
