Trigger Level
Used with Video and RF Burst triggering, a sweep is initiated when an
incoming signal crosses this level. See also
RF Burst Trigger Level uses an alignment process which is performed in the
background to set the detected signal level accuracy. Video Trigger Level is a
comparison done on the time domain signal, before conversion to the spectral
frequency domain. Processing from the time to frequency domain can cause
broadband (e.g., pulsed) signal energy to display at lower power levels than
the peak power levels of the time domain signal. Therefore you may need to
the set trigger level higher than the displayed spectral level.

When Auto Trigger is OFF, the FieldFox does NOT sweep unless a valid trigger
signal is received.
