(1) Input 0.3V synchronizing signal to pin 51 (Sync IN).
(2) Supply 5V of external supply voltage to pin 22 (Analog Ys).
(3) Set bus data on drive at center value.
(4) Input TG7 sine wave signal (f = 100kHz, video amplitude = 0.5V) to
pin 23 (Analog R IN).
(5) While changing data on RGB contrast from maximum (FF) to
minimum (00), measure maximum and minimum amplitudes of pin
14 (R OUT) in video period. At the same time, measure video
amplitude of pin 14 when the bus data is set at the center value
(80). (Vc14mx, Vc14mn, D14c80)
(6) In the same manner as the above steps 4 and 5, measure output
signal of pin 13 with input of the same external power supply to pin
24 (Analog G IN), and measure output signal of pin 12 with input of
the same power supply to pin 25 (Analog B IN). (Vc12mx, Vc12mn,
D12c80).
(7) Find amplitude ratio between signal with maximum unicolor data
and signal with minimum unicolor data in conversion into decibel
(
V13ct).
