—Gate Delay Effectively moves the gating area left (negative delay) or
right (positive delay) relative to the trigger event. Enter a value using
the numeric keypad, the arrows, or the rotary knob.
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

signals and the slower the sweep speed.
How to set number of points
