Start/Length of Fence ← Config Fence …
Within the measurement period, a "fence", i.e. an exclusion interval, can be set. The fence
is defined by its start time and length. The start time refers to the start of a timeslot.

4.2.1.5 Measuring the average power in gates
The timegate mode is used to measure the average power in arbitrarily chosen time
intervals (gates). The time resolution is determined by the sampling rate of the sensor.
Up to four different gates can be defined, although measurement can be performed only
in one of them at a time. The "T'gate Av" mode is set and configured in this dialog box.
The active gate must be selected in the dialog box "Func
& Unit", see
​
chapter 4.4.3,
"Selecting a measurement function" , on page 98.
The R&S NRP-Z8x wideband power sensors can additionally define an exclusion interval
within the gate (Fence). A midamble of the signal can thus be excluded from the mea-
surement.
An external trigger signal or internal signal triggering is required for synchronization, see
also
​
chapter 4.2.6, "Trigger settings" , on page 85.
► Select "T'gate Av" in the "Mode..." dialog box opened via the "Sensor" menu.

Gate
Sets the number of the gate to be configured.
Note: In remote control, the gate to be configured is determined by the
TGATe
suffix, see
commands for the following settings.
Start/Length of Gate
Start of the gate is referenced to the delayed trigger time, see
