(1)
Input TG7 sine wave signal whose frequency is 6MHz 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 contrast is maximum, Y sub contrast and
drive are set at each center value and color is minimum.
(5)
Measure amplitude of pin 13 signal (G OUT) and find the
output / input gain (double) (G6M).
(6)
From the results of the above step 5 and the Note T3, find the
frequency characteristic.
Gf = 20og (G6M / G)
