Control Edge/Level
Sets the method of controlling the gating function from the gating signal.
Edge
In Edge triggering, the gate opens (after the Delay) on the selected edge (for example, positive) of the
gate signal and closes on the alternate edge (for example, negative).
Level
In Level triggering, the gate opens (after the Delay) when the gate signal has achieved a certain level and
stays open as long as that level is maintained.

Gate Holdoff
Lets you increase or decrease the wait time after a gate event ends before the analyzer will respond to the
next gate signal.
After any Gate event finishes, the analyzer must wait for the sweep system to settle before it can respond
to another Gate signal. The analyzer calculates a "wait time," taking into account a number of factors,
including RBW and Phase Noise Optimization settings. The goal is to achieve the same accuracy when
gated as in ungated operation. The figure below illustrates this concept:

If the Gate Method is FFT the Control key is grayed out and Edge is selected.
If the Gate Source is TV, Frame or Line, the Control key is grayed out and
Edge is selected.
