(1)
Short circuit pin 31 (Y IN), pin 33 (B-Y IN) and pin 34 (R-Y IN)
in AC coupling.
(2)
Input 0.3V synchronizing signal to pin 51 (Sync IN).
(3)
Set bus data so that R, G, B cut off data are set at center
value.

(4)
Connect pin 21 (Digital Ys) and pin 22 (Analog Ys) to ground.
(5)
While changing bus data on brightness from maximum to
minimum, measure video voltage of pin 13 (G OUT) to find
maximum and minimum voltages (max : Vbrmx, min : Vbrmn).
(6)
With bus data on brightness set at center value, measure
video voltage of pin 13 (G OUT) (Vbcnt).

(7)
On the conditon that bus data with which Vbrmx is obtained in
measurement of the above step 5 is Dbrmx and bus data with
which Vbrmn is obtained in measurement of the above step 5 is
Dbrmn, calculate sensitivity of brightness data (Vbrt).
Vbrt = (Vbrmxg Vbrmng) / (Dbrmxg Dbrmng)

maximum and brightness is minimum.
(2)
Input TG7 sine wave
signal whose frequency is
100kHz and amplitude in
video period is 0.9V to pin
31 (Y IN).
(3)
Connect pin 21 (Digital Ys)
and pin 22 (Analog Ys) to
ground.
(4)
While turning on / off WPL
with bus, measure video
amplitude of pin 14 (R OUT) with WPL being activated (Vwpl).
