2) Apply an external power supply to pin 6. Gradually increase the voltage
from 0 V.
3) When signal 1 is output to pin 13, measure the voltage of pin 6.
1) Set the subaddress (05, RGB brightness) data to the maximum (F8).
2) Input signal 3 (signal amplitude 4.5 V_p-p) to pin 6.
3) Measure the switching transfer characteristics of pins 13, 14, and 15

according to diagram T-2.
4) Using the data obtained from the above measurements, calculate the
maximum axis difference between the rising and falling edges of transfer
delay time.
1) Input signal 1 (f = 4 MHz, picture period amplitude = 0.5 V_p-p) to pin 54.
2) Adjust the input amplitude so that the picture period amplitude of pin 13
is 2 V_p-p.

5) Calculate by the following formula the amount of crosstalk from the video
to the analog RGB.
Vv → AR = −20 × ℓog (v_13A / 2)
6) Repeat steps 4) and 5) above on pins 14 and 15.
