Triggering the Oscilloscope
To use TV triggering
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 trigger Holdoff softkey
in the trigger Mode/Coupling menu. Using the holdoff settings shown in the
following table, the oscilloscope will now trigger on color field 1 OR color field
3 when Field 1 is selected. This is known as odd field selection. Even fields will
be selected with Field 2.
