be displayed on Channel 2 although other timing
comparisons may be desired.
Waveforms No. 11 through No. 13 would probably
be displayed on Channel 2 in relationship
waveform No. 8 or No. 4 on Channel 1. In the
family of time-related waveforms shows in Fig. 9,
waveform No. 8 or No. 10 is an excellent sync
source for viewing all of the waveforms; there is
but one triggering pulse per frame.

Waveforms No. 4 through No. 7 should not be used
as the sync source because they do not contain a

triggering pulse at the start of the frame. It would
not be necessary to view the entire waveforms as
shown in Fig. 9 in all cases. In fact, there are many
times when a closer examination of a portion of the
waveforms would be appropriate. In such cases, it
is recommended that the sync remain unchanged
