(1) In the condition of the Note Y14, set the picture quality control bus data to
minimum.
(2) Perform the same measurement as the steps 3 through 8 of the Note Y14 to find
respective gains as the picture quality control frequency is set to 2.5 MHz, 3.1 MHz
and 4.2 MHz.
GS25MN = 20 og (Vp25 / V100k)
GS31MN = 20 og (Vp31 / V100k)
GS42MN = 20 og (Vp42 / V100k)

(1) In the condition of the Note Y14, set the picture quality control bus data to center.
(2) Perform the same measurement as the steps 3 through 8 of the Note Y14 to find
respective gains as the picture quality control frequency is set to 2.5 MHz, 3.1 MHz
and 4.2 MHz.
GS25CT = 20 og (Vp25 / V100k)

(1) Set the bus data so that black expansion is off, picture quality control is off and DC
transmission compensation is minimum.
(2) Input TG7 sine wave signal whose frequency is 100 kHz and video level is 0.5 V to
pin 45 (Y1 IN) and pin 48 (Sync. IN). (Vyi100)
(3) Measure amplitude of Y1 output at pin 37 (Vyout).
Gy = 20 og (Vyout / Vyi100)
Y18

Characteristic
↑
(1) Set the bus data so that black expansion is off, picture quality control is off and DC
transmission compensation is minimum.
(2) Input TG7 sine wave signal whose frequency is 6 MHz and video level is 0.5 V to
pin 45 (Y1 IN) and pin 48 (Sync. IN). (Vyi6M)
(3) Measure amplitude of Y1 output at pin 37 (Vyo6M).
Gy6M = 20 og (Vyo6M / Vyi6M)
(4) Find Gfy from the result of the Note Y17
Gfy = Gy6M Gy
