Video Trigger
Video triggering can be used to capture the complicated waveforms of
most standard analog video signals. The trigger circuitry detects the
vertical and horizontal interval of the waveform and produces triggers
based on the video trigger settings you have selected.
The oscilloscope's MegaZoom IV technology gives you bright, easily viewed
displays of any part of the video waveform. Analysis of video waveforms is
simplified by the oscilloscope's ability to trigger on any selected line of the
video signal.
1 Press the [Trigger] key.
It is important, when using a 10:1 passive probe, that the probe is correctly compensated.
The oscilloscope is sensitive to this and will not trigger if the probe is not properly
compensated, especially for progressive formats.
