15.5.5 Video Trigger
Video trigger 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
a trigger based on the video trigger settings you have selected. The SDS2000X HD supports standard
video signals 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.
Touch the Standard and select the video standard. The SDS2000X HD supports the following
video standards:
TV Standard
Scan Type
Sync Pulse
NTSC Interlaced Bi-level
PAL Interlaced Bi-level
HDTV 720P/50 Progressive Tri-level
