1)
Turn SW6 on.
2)
Input signal 1 (f = 4MHz, picture period amplitude = 0.5 Vp-p) to pin 3.
3)
Adjust the input amplitude so that the picture period amplitude of pin 13
is 2 Vp-p.
4)
Turn SW6 off.
5)
Measure the picture period amplitude (Vp-p) of pin 13. (v13B)
6)
Calculate by the following formula the amount of crosstalk from the
analog RGB to the video.
vA → AR = 20 × og (v13B / 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

C
1)
Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 Vp-p) to pin 7.
2)
Measure the picture period amplitude of pin 13. (v13R)
3)
As in steps 1) and 2) above, input to pin 8 and measure pin 14, then
input to pin 9 and measure pin 15. (v14G, v15B)
4)
GOSDR = v13R / 0.2
GOSDG = v14G / 0.2
GOSDB = v15B / 0.2

1)
Input signal 1 (f = 8 MHz, picture period amplitude = 0.2 Vp-p) to pin 7.
2)
Measure the picture period amplitude of pin 13. (v13R 8MHz)
3)
As in steps 1) and 2) above, input to pin 8 and measure pin 14, then
input to pin 9 and pin 15. (v14G 8 MHz, v15B 8 MHz)
4)
Calculate the frequency characteristics from the above results and the
results in T37.
5)
GfOSDR = 20 × og (v13R 8 MHz / v13R)
GfOSDG = 20 × og (v14G 8 MHz / v14G)
GfOSDB = 20 × og (v15B 8 MHz / v15B)
