2-4. SETUP FOR ADJUSTMENT
For adjustment of the VTR section, the video signal from
the pattern generator is used as the adjustment signal.
Therefore, it is necessary that this video output signal is
within the specified level.
Confirm that the amplitude of the sync signal of the video
signal is about 0.3 Vp-p, that the amplitude of the video
section is about 0.7 Vp-p, that the amplitude of the burst
signal is about 0.3 Vp-p and is flat, and that the level ratio of
the burst signal and the "red" signal is 0.30 : 0.66.
