More Information
For Video Trigger Level, when sweep type = FFT, the video trigger uses the
amplitude envelope in a bandwidth wider than the FFT width as a trigger source.
This can be useful but does not have the same relationship between the displayed
trace and the trigger level as in swept triggering.
For Video Trigger Level the settable resolution of the function is 0.01dB, even when
the Y Axis Unit is linear. In Linear Y Axis Unit (for example, Volts) this requires 4
significant digits to display on the control.
