Measurement Gate
A gate, controlled by and referenced to a trigger point, is used to extract
measurement data from the captured trace. You can measure the gated
average power of pulsed signals with the gate setup as shown in
Figure 2- 2 on page 24.

It is strongly recommended for the gate to have 150 µs (range settling time) offset from the
pulse rising edge and 40 µs (fall time) offset from the pulse falling edge to achieve higher
accuracy measurements. Samples collected during range settling time are discarded. Thus,
fewer samples are used for generating a measurement.
