Sync:
Press Sync, then rotate the multifunction knob to select the sync type, and then
press down the knob to select the type. You can also press Sync continuously to
select the sync type or enable the touch screen to tap the desired sync type and
select it.
All Lines: triggers on the first line found.
Line: for NTSC and PAL/SECAM video standards, trigger on the specified line.
When this sync type is selected, you can specify a line number. Press Line, then
rotate the multifunction knob or use the pop-up numeric keypad to modify
the line number. The range of the line number is related to the currently selected
video standards. The range is from 1 to 525 (NTSC), 1 to 625 (PAL/SECAM), 1 to
525 (480P), and 1 to 625 (576P).
Odd: triggers on the rising edge of the first ramp pulse in the odd field.
Even: triggers on the rising edge of the first ramp pulse in the even field.
Noise Rejection:
Set the trigger parameter (noise rejection) under this trigger type. For details, refer
to descriptions in "Noise Rejection".
Trigger Mode:
In the trigger control area (Trigger) on the front panel, press Mode to quickly switch

Tip
For a better observation of the waveform details in the video signal, you can
set a larger memory depth first.
In the trigger debugging process of video signals, the frequency in different
part of the signal can be reflected by a different brightness, as RIGOL digital
oscilloscope provides the intensity graded color display function. Experienced
users can quickly judge the signal quality and discover abnormalities during
the debugging process.
