The best way to tell is to look at the last line of video in each
of the fields. In one field the last line will be 64 usec long
whereas the other field will be 32 usec.

If your scope is equipped with video trigerring, this will be a
snap, if not, try to get two fields on the screen and then use
the delay to hunt around.
