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).
