1)
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 200 mVp-p : 200 mVp-p.
2)
Now set as follows :
Unicolor
: maximum (subaddress (00H), data (3F))
Brightness
: maximum (subaddress (01H), data (7F))
Color
: center (subaddress (02H), data (40))
Relative phase amplitude
: standard (subaddress (12H), data (00)).
3)
Measure the amplitudes vRo, vGo, and vBo of the R output pin (TP13), the G output pin (TP14), and the B output pin
(TP15).
4)
Set SW6 to B and repeat the test in 3) above. Measure the amplitudes vRH, vGH, and vBH.
5)
Calculate the half-tone characteristics vRHo, vGHo, and vBHo by the following formulas.
