MEASUREMENT METHOD
1) Turn SW₆ on.
2) Input signal 1 (f = 4MHz, picture period amplitude = 0.5 V_p-p) to pin 3.
3) Adjust the input amplitude so that the picture period amplitude of pin 13
is 2 V_p-p.

5) Measure the picture period amplitude (V_p-p) of pin 13. (v_13B)
OFF
6) Calculate by the following formula the amount of crosstalk from the
analog RGB to the video.
vA → AR = −20 × ℓog (v_13B / 2)
7) As in steps 2) to 6) above, input to pin 4 and measure pin 14, then input
to pin 5 and measure pin 15
