MEASURING METHOD
(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).

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
(Mnr-b = Vu14mx / Vu12mx, Mng-b = Vu13mx / Vu12mx).

(1) 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).
