(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.
Also, measure the
respective amplitudes with
the bus data set to the
center value (80).

(6)
Find ratio between amplitude with maximum unicolor and that
with minimum unicolor in conversion into decibel (V13ct).

In the test condition of Note T2, find output / input gain (double) with
maximum contrast.
