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.

3) Switch the relative phase amplitude (subaddress (12H)) and measure the amplitudes (peak values) of the
RGB outputs (TP13, TP14, TP15) according to the table below.
