Test Conditions
1) Set the subaddress (10) data to (20).
2) Input signal 3 (f₀ = 100 kHz, picture period amplitude = 0.2 V_p-p) to pin 1.
3) Measure the picture period amplitude of the waveform output from pin 11.
(vHTA_RY)
4) Apply 1.5 V from an external power supply to pin 6.

6) GHT_RY = vHTB_RY/vHTA_RY
7) Repeat steps 1) to 5) above with pin 13.
GHT_GY = vHTB_GY/vHTA_GY
8) Repeat steps 1) to 5) above, inputting signal to pin 80 and measuring pin
15.
