(1) Short circuit pin 31 (Y IN), pin 34 (R-Y IN) and pin 33 (B-Y IN) in
AC coupling.
(2) Input 0.3V synchronizing signal to pin 51 (Sync IN).
(3) Measure voltage at pin 31, pin 34 and pin 33 (Vcp31, Vcp34,
Vcp33).
(1) Input TG7 sine wave signal whose frequency is 100kHz and video
amplitude is 0.7V to pin 31 (Y IN).
(2) Input 0.3V Synchronizing Signal to pin 51 (Sync IN).
(3) Connect both pin 21 (Digital Ys) and pin 22 (Analog Ys) to ground.
(4) Set bus data so that Y sub
contrast and drive are set at
each center value and color is
minimum.
(5) Varying data on contrast from
maximum (FF) to minimum (00),
measure maximum and
minimum amplitudes of
respective outputs of pin 14 (R
OUT), pin 13 (G OUT) and pin
12 (B OUT) in video period, and
read values of bus data at the
same time.
