In the setting condition of the Note T52, calculate output / input gain
(double) with contrast data being set maximum.
G = Vc13mx / 0.5 V

(1) Input 0.3 V synchronizing signal to pin 48 (Sync IN).
(2) Supply 5 V of external supply voltage to pin 22 (Analog Ys).
(3) Input TG7 sine wave signal (f = 100 kHz, video amplitude = 0.5 V)
to pin 24 (Analog G IN).
(4) Set bus data so that contrast is maximum and drive is set at center
value.
(5) Measure video amplitude of pin 13 (G OUT) and calculate output /
input gain (double) (G6M).
(6) From measurement results of the above step 5 and the preceding
Note 53, find frequency characteristic.
Gf = 20 og (G6M / G)
