8. Timing Accuracy
Be sure that SWEEP is still 2LINE. Hold the REF button in until the CAL signal
appears. Position it so the top of the display is on the 70 IRE (NTSC) or 0.7 V
(PAL). Horizontally position the display so the first transition is on the left side
timing mark (the mark that goes completely through the blanking line. There are
three on the graticule.) See Figure 1–14a. Check that the falling transition of the
10
th
square wave passes directly through the right side timing mark. The H CAL
can be adjusted if timing is off. Push the MAG button and check for one cycle of
square wave over the 10 divisions of timing area. See Figure 1–14b.
Hold the SWEEP button until the 1 LINE front-panel indicator lights. Check for
five full cycles over the 10-division timing area. See Figure 1–14c.
Push the waveform monitor REF switch and return to INT.
