When this sync type is selected, you can specify a line number. Click or tap the
input field of Line to set the line number with the pop-up numeric keypad. You
can also use the specified knob to set it. 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), 1 to 625 (576p), 1 to 750 (720p), or 1 to 1125
(1080p/1080i).
• Odd: triggers on the rising edge of the first ramp pulse in the odd field. It is only
available when the video standard is set to "NTSC" or "PAL/SECAM".
• Even: triggers on the rising edge of the first ramp pulse in the even field. It is
only available when the video standard is set to "NTSC" or "PAL/SECAM".
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's digital oscilloscope provides
the intensity graded color display function. Experienced users can quickly judge the
signal quality and discover abnormalities during the debugging process.
8.7.5 Pattern Trigger
Identifies a trigger condition by searching for a specified pattern. This pattern is a
logical "AND" combination of channels. Each channel can be set to H (high), L (low),
or X (don't care). A rising or falling edge (you can only specify a single edge) can be
specified for one channel included in the pattern. When an edge is specified, the
oscilloscope will trigger at the edge specified if the pattern set for the other channels
are true (namely the actual pattern of the channel is the same as the preset pattern). If
no edge is specified, the oscilloscope will trigger on the last edge that makes the
pattern true. If all the channels in the pattern are set to "X", the oscilloscope will not
trigger.
