Sweep/Control
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:
When Gate Holdoff is in Auto, the wait time calculated by the analyzer is used. When Gate Time is in
Manual, the user may adjust the wait time, usually decreasing it in order to achieve greater speed, but at
the risk of decreasing accuracy.
When the
Method key is set to Video or FFT, the Gate Holdoff function has no effect.
In measurements that do not support Auto, the value shown when Auto is selected is “---“ and the
manually set holdoff is returned to a query.
