(1)
Input 0.3V synchronizing signal to pin 51 (Sync IN).
(2)
Input 100kHz, 0.3Vp-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
drive is at center
value and Y mute is
on.
(5)
While changing bus
data on unicolor from
maximum (FF) to
minimum (00),
measure maximum
and minimum amplitudes of pin 13 (G OUT) and pin 12 (B
OUT) in video period respectively, and read the bus data
together with.,
Also, measure respective amplitudes as unicolor data is set at
center value (80).

Find ratio between amplitude with maximum unicolor data and
that with minimum unicolor data in conversion into decibel
(V13un).

While inputting rainbow color bar signal (3.58MHz for NTSC) 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.

In the test condition of the Note T8, 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 (θnr-b,
θng-b).
