2. Input signal 3 (f₀ = 100 kHz, picture period amplitude = 0.115 Vp-p) from pin 66.
3. Change color data to maximum (7F), center (40), and minimum (01), and
measure pin 12 picture period amplitudes V_CCYMAX、V_CCYCNT, and V_CCYMIN
respectively.
4. Calculate amplitude ratios of maximum and minimum against color center in
decibels. (∆V_CCY)
5. Repeat the steps 2 to 4 above with the following pins: Input (picture period
amplitude 0.1Vp-p) from pin 67 and measure pin 14.

3. Apply 1.5 V to pin 79 from external power supply.
4. Measure pin 12 output picture period amplitude vHTBRY.
5. Calculate GHT_RY = vHTBRY/vHTARY
6. Repeat the steps 1 to 5 above and measure pin 13.
Calculate GHT_GY = vHTBGY/vHTAGY
7. Repeat the steps 1 to 5 above and measure pin 67. Calculate GHT_BY =
vHTBBY/vHTABY.
