(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 2.5MHz, 3.1MHz
and 4.2MHz.
GS25MN = 20og (Vp25 / V100k)
GS31MN = 20og (Vp31 / V100k)
GS42MN = 20og (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 2.5MHz, 3.1MHz
and4.2MHz.
GS25CT = 20og (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 100kHz and video level is 0.5V to
pin 45 (Y1 IN) and pin 51 (Sync. IN). (Vyi100)
(3) Measure amplitude of Y1 output at pin 37 (Vyout).
Gy = 20og (Vyout / Vyi100)
Y18
Y Signal Frequency
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 6MHz and video level is 0.5V to pin
45 (Y1 IN) and pin 51 (Sync. IN). (Vyi6M)
(3) Measure amplitude of Y1 output at pin 37 (Vyo6M).
Gy6M = 20og (Vyo6M / Vyi6M)
(4) Find Gfy from the result of the Note Y17.
Gfy = Gy6M Gy
