(1)
Connect both pin 21 (Digital Ys) and pin 22 (Analog Ys) to
ground.
(2)
Input TG7 sine wave signal whose frequency is 100kHz and
video amplitude is 0.7V to pin 31 (Y IN).
(3)
Input 0.3V synchronizing signal to pin 51 (Sync IN).
(4)
Set bus data so that contrast is maximum, drive is set at
center value and color is minimum.
(5)
Set bus data on Y sub contrast at maximum (FF) and
measure amplitude (Vscmx) of pin 14 output (R OUT). Then,
set data on Y sub contrast at minimum (00), measure the
same (Vscmn).
(6)
From the results of the above step 5, find ratio between
Vscmx and Vscmn in conversion into decibel (Vscnt).

(1)
Set bus data so that contrast is maximum, Y sub contrast and
drive are at each center value.
(2)
Input 0.3V synchronizing signal to pin 51 while inputting TG7
sine wave signal whose frequency is 100kHz to pin 31 (TY
IN).
(3)
While increasing the amplitude of the sine wave signal,
measure video amplitude of signal 1 just before R output of
pin 14 is distorted. (Vy2d)
