While inputting rainbow color bar signal (4.43MHz for PAL) to pin 42 and
0.3V synchronizing signal to pin 51 so that video amplitude of pin 33 is
0.38Vp-p, find the relative amplitude.
(Mpr-b = Vu14mx / Vu12mx, Mpg-b = Vu13mx / Vu12mx)

(1) In the test condition of the Note T10, adjust bus data on tint so that
output of pin 12 (B OUT) has the peak level in the 6th bar.
(2) Regarding the phase of pin 12 (B OUT) as a reference phase, find
comparative phase differences of pin 14 (R OUT) and pin 13
(G OUT) from the reference phase respectively (θpr-b, θpg-b).

(1) Input 0.3V synchronizing signal to pin 51 (Sync IN).
(2) Input 100kHz, 0.1Vp-p sine wave signal to both pin 33 (B-Y IN) and
pin 34 (R-Y IN).
(3) Connect pin 21 (Digital Ys) and pin 22 (Analog Ys) to ground.
(4) Set bus data so that unicolor is maximum, drive is at center value
and Y mute is on.
(5) Measure amplitude of pin 12 (B OUT) as bus data on color is set
maximum (FF). (Vcmx)
(6) Read bus data when output level of pin 12 is 10%, 50% and 90%
of Vcmx respectively (Dc10, Dc50, Dc90).

(7) From results of the above step
6, calculate number of steps
from Dc10 to Dc90 (col) and
that from 00 to Dc50 (ecol).
(8) Measure respective
amplitudes of pin 12 (B OUT),
pin 13 (G OUT) and pin 14
(R OUT) with color data set at
minimum, and regard the
results as color residuals (ecb,
ecg, ecr).
