To indicate that a gate is used for the sweep, "GAT" and the gate source is displayed
in the channel bar.
7.7.2.2 Gate Settings
Gate settings define one or more extracts of the signal to be measured.
Gating is not available for measurements on I/Q-based data.
Gated Trigger ............................................................................................................. 417
Gate Mode ................................................................................................................. 417
Gate Delay ................................................................................................................. 417
Gate Length ............................................................................................................... 418
Gated Trigger
Switches gated triggering on or off.
If the gate is switched on, a gate signal applied to one of the TRIGGER INPUT connec-
tors or the internal IF power detector controls the sweep.
Gate Mode
Sets the gate mode.
For more information see Chapter 7.7.2.1, "Gated Measurements" , on page 414
"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.
Note: If you perform gated measurements in combination with the IF
Power trigger, the R&S FPL1000 ignores the holding time for fre-
quency sweep, FFT sweep, zero span and I/Q mode measurements.

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" .
