Trigger Delay
After a valid External or Video trigger signal is received, the sweep begins after
the specified Trigger Delay time. Only positive values are allowed.
To see the rising edge of a repetitive signal which is triggered on that edge, use
trigger delay to clearly view the subsequent signal one period later.

Trigger Level
Used with Video triggering, an incoming signal with this amplitude or higher
(for positive slope) will initiate a sweep. The Units depend on the Scale Type
setting: (Log or Linear). Learn more in
The Video Trigger Level is a time domain (Zero Span) signal level comparison.
Therefore, the sweep will trigger close to the displayed level in Zero Span
measurements. In frequency span measurements, processing can cause
broadband signal energy to display at lower power levels than the originating
time domain signal. Therefore, you may need to set the trigger level higher
than the displayed level.

Auto Trigger Time
If an External or Video trigger signal is not received before the specified Auto
Trig Time, a sweep will occur automatically.
Enter 0 to set Auto Trigger OFF. When Auto Trigger is OFF, the FieldFox does
NOT sweep unless a valid External or Video trigger signal is received.
