Triggering on Odd or Even Video Fields
Your oscilloscope will trigger on both odd and even video fields, and
make the data difficult to view because the line details are a half line
apart. To remedy this, you can set the holdoff period to lock on just
the odd or even field, which produces a stable display.
For example, the field rate for NTSC video is 60 Hz. For stable
triggering, you should set the holdoff period to at least the field rate
(16.7 ms), but not to more than twice the field rate (33 ms).
