Set-up of Adjustment
In this adjustment, PAL or NTSC pattern generator is connected
with LINE input signal terminal. When checking with tuner, con-
nected AERIAL terminal. Check that the amplitudes of video sig-
nal 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. 7-3-2.
