9-1-6. Checking the Input Signals
Because the video signal obtained from the pattern generator is
used as the adjustment signal for adjusting the VTR section, the
video output signal must satisfy the given specifications.
1.
VIDEO input
Connect the oscilloscope to the video output terminal, and
check that the sync signal amplitude of the video signal is
approximately 0.3V, the amplitude of the video se~tion ~s
approximately 0.7V, the amplitude of the burst signal
IS
approximately 0.3V and flat, and that the level ratio of the burst
