(1)
Short circuit pin 33 (B-Y IN) and pin 34 (R-Y IN) in AC
coupling.
(2)
Input such the step-up signal as shown below to pin 45 (Y IN)
and pin 51 (Sync IN).
(3)
Connect pin 21 (Digital Ys) and pin 22 (Analog Ys) to ground.
(4)
Set bus data so that contrast is maximum and DC
transmission correction factor is minimum.
(5)
Adjust data on Y sub contrast so that video amplitude of pin
13 (G OUT) is 2.5V.
(6)
While varying APL of the step-up signal from 10% to 90%,
measure change in voltage at the point A.
