Figure 19 Triggering on Color Field 1 Alternating with Color Field 3
If a more detailed analysis is required, then only one color field
should be selected to be the trigger. You can do this by using the
TV Holdoff softkey in the trigger More Trigger Menu when the
trigger type is set to TV. Press the TV Holdoff softkey and use the
Entry knob to adjust the holdoff in half-field increments until
the oscilloscope triggers on only one phase of the color burst.
A quick way to synchronize to the other phase is to briefly
disconnect the signal and then reconnect it. Repeat until the
correct phase is displayed.
When holdoff is adjusted using the TV Holdoff softkey and the
Entry knob, the corresponding holdoff time will be displayed in
the Mode/Coupling menu.
