Set-up of Adjustment
In this adjustment, PAL-N or NTSC pattern generator is connected
with LINE input signal terminal. When check to tuner, connected
AERIAL terminal. Check that the amplitudes of video signal SYNC
signal, of picture portions, and of burst signals are flat at
approximately 0.3, 0.7 and 0.3 V, respectively, and that the level
ratio of the burst signal and “red” signal are 0.30: 0.66. Fig. 7-2-2.
