The trigger circuitry detects the vertical andhorizontal interval of the waveform and produces triggers based on the videotrigger settings you have selected.The oscilloscope's MegaZoom IV technology gives you bright, easily vieweddisplays of any part of the video waveform. Analysis of video waveforms issimplified by the oscilloscope's ability to trigger on any selected line of the videosignal.1 Press the [Trigger] key.2 In the Trigger Menu, press the Trigger softkey; then, turn the Entry knob toselect Video.NOTE It is important, when using a 10:1 passive probe, that the probe is correctly compensated. Theoscilloscope is sensitive to this and will not trigger if the probe is not properly compensated,especially for progressive formats.
