Set to external color difference input mode (subaddress (05H), data (81)).
Now set as follows :
Unicolor

Relative phase amplitude :
Y mute
Set SW
Set the color to the minimum and measure the picture period DC voltage v
Increase the color from the minimum. When the picture period DC voltage of the R output pin (TP13) changes, measure
the picture period DC voltage v
Using the values obtained above, calculate the color γ start point C
