— Depress push-button "PHASE".
•
Adjust both demodulator phases to obtain an oscillogram as shown
in Fig. VII-33.
Figs. VII-34, VII-35 and VII-36 show oscillograms that will be obtained
in case of incorrectly adjusted demodulators. If the (R-Y) signal
cannot be made correct for both successive TV lines, the (R-Y) switch
of the receiver does not switch exactly 180.
Note: The time base speed of the oscillograms is approx. 6.5 µs/division.
