Connect an oscilloscope to the Video Input terminal. Check that the
synchronizing signal of the Y signal has an amplitude of
approximately 0.7V and that the burst signal has an amplitude of
approximately 0.3V and its waveform is flat. And check that the
level ratio of burst signal to “red” signal is 0.30 : 0.66. The video
signal (color bar) used for electrical aligning this unit is shown in
Fig. 6-2-2.
