The end of the gate is determined by the start time and the length of the gate.

Fence
Activates the "Fence" function.
In numeric T'slotAv mode, the "Fence" function is only available for the wideband power
sensors of the R&S NRP-Z8x series. For all other sensors, a fence can be used in the
"T'slots" display in the Trace&Statistics sensor mode.
Config Fence …
Opens the dialog box for setting the parameters "Start" and "Length".

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 of Fence" refers to the start of the gate.

4.2.1.6 Trace & statistics measurements
The "Trace & Statistics" mode is used to display the time characteristic of the envelope
power and its statistical distribution. For further information on its configuration and oper-
ation, refer to
​
chapter 4.5, "Displaying traces" , on page 112.
4.2.1.7 Background information on power measurement
This chapter provides some background information on power measurement in "Cont
Av", "T'slot Av", "T'gate Av" and "Burst Av" mode, smoothing, or what is the point of
dropout tolerance. Additionally, timing diagrams explain visually the relation between
trigger, aquisition intervals and excluded time segments in "T'gate" or "T'slot" measure-
ment mode.
Acquisition interval
As the sensor amplifiers use chopping, a measurement always contains an integer mul-
tiple of a pair of acquisitions which are taken with opposite polarity of the detector output
