To set up video triggers
Video triggering is used to trigger on fields or lines of NTSC, PAL, or
SECAM standard video waveforms.
When the video trigger mode is selected, the trigger coupling is set to AC.
1 Press Mode/Coupling
.
2 In the Trigger menu, press Mode until “Video” is selected.
3 Select Polarity to toggle between:
• Normal polarity — trigger on the negative edge of the sync pulse.
• Inverted polarity — trigger on the positive edge of the sync pulse.
4 Press Sync to select what to trigger on:
• All Lines — trigger on all lines.
• Line Num — trigger on a selected line.
If you select “Line Num”, select the following Line Num menu item and
turn the Entry
knob to select the line number.
• Odd Field — trigger on an odd field.
• Even Field — trigger on an even field.
5 Select Standard to toggle between:
• NTSC — trigger on an NTSC video waveform.
• PAL/SECAM — trigger on a PAL or SECAM video waveform.
NOTE
Normal Polarity Sync triggers always occur on negative-going horizontal sync pulses. If the
video waveform has positive-going horizontal sync pulses, use the Inverted Polarity
selection.
