When you have properly setup the Gate Trigger, Width, and Delay using the Gate
View measurement, you can turn Gate View OFF to return to the full screen non-
zero span measurement with FFT Gating ON, the RBW set, and the Trigger
settings active.

NOTE
The following behavior is unique to SA Mode.
This setting determines whether the FieldFox measures continuously or only
once each time the

Then choose one of the following:
Points
Points is the number of measurements that are displayed along the X-axis. The
higher number of data points, the better the ability to resolve closely spaced
signals and the slower the sweep speed.

Gate Width
Set the width of the gating area within the non-zero span
