waveforms No. 4 through No. 8 and No. 10, wouldbe displayed on Channel 2 although other timingcomparisons may be desired.Waveforms No. 11 through No. 13 would probablybe displayed on Channel 2 in relationship towaveform No. 8 or No. 4 on Channel 1. In thefamily of time-related waveforms shows in Fig. 9,waveform No. 8 or No. 10 is an excellent syncsource for viewing all of the waveforms; there isbut one triggering pulse per frame. For con-venience, external sync using waveform No. 8 orNo. 10 a s the sync source may be desiable.With No. 8 or No. 10 used as external sync source.any of the waveforms may be displayed withoutreadjustment of the T R I G L E V E L control.Waveforms No. 4 through No. 7 should not be usedas the sync source because they do not contain atriggering pulse at the start of the frame. It wouldnot be necessary to view the entire waveforms asshown in Fig. 9 in all cases. In fact, there are manytimes when a closer examination of a portion of thewaveforms would be appropriate. In such cases, itis recommended that the sync remain unchangedwhile the sweep speed or X 5 MAG control is usedto expaned the waveform display.1 S T A R T3 C L O C K4 D A T A S E L E C T " A "5 D A T A S E L E C T " B " -6 D A T A S E L E C T " C " •7 D A T A S E L E C T " D "8 D A T E E N A B L E •9 R U N12L I N E D R I V E RO .
