MEASUREMENT METHOD
1) Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 _Vp-p) to pin 3.
2) Measure the picture period amplitude of pin 13 (v_13R).

3) As in steps 1) and 2) above, input to pin 4 and measure pin 14 (v_14G),
then input to pin 5 and measure pin 15 (v_15B).
4) G_TXR = v_13R / 0.2
G_TXG = v_14G / 0.2
G_TXB = v_15B / 0.2
1) Input signal 1 (f = 8 MHz, picture period amplitude = 0.2 V_p-p) to pin 3.
2) Measure the picture period amplitude of pin 13. (v_13R 8 MHz)

4) Calculate the frequency characteristics from the above results and the
results obtained in T₂₆.
Gf_TXR = 20 × ℓog (v_13R 8 MHz / v_13R)
Gf_TXG = 20 × ℓog (v_14G 8 MHz / v_14G)
Gf_TXB = 20 × ℓog (v_15B 8 MHz / v_15B)
1) Set the subaddress (00 : unicolor) data to min (00).
2) Input signal 2 to pin 3 and gradually increase picture amplitude A.
3) When the voltage during the picture period of pin 13 stops changing,
measure picture amplitude A (DR13).

4) Repeat steps 2) and 3) above under the following conditions :
Input to pin 4, measure the voltage during the picture period of pin 14
(DR14).
Input to pin 5, measure the voltage during the picture period of pin 15
(DR15).
