15.5.5 Video Trigger

The video trigger can be used to capture the complicated waveforms of most standard
analog video signals. The trigger circuitry evaluates the vertical and horizontal interval
of the waveform based on the video trigger settings you have selected. The
T3DSO2000A supports standard video signal for NTSC (National Television Standards
Committee), PAL (Phase Alternating Line), HDTV (High Definition Television) and a
custom video signal trigger.
Source, standard and synchronization mode can be set in the video trigger dialog box.
When the synchronization mode is "Select", line and field can be specified.
