MEASUREMENT METHOD
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 200 mV_p-p : 200 mV_p-p.
Now set as follows :
Unicolor
:
Brightness
:
Relative phase amplitude :
maximum (subaddress (00H), data (3F))
maximum (subaddress (01H), data (7F))
standard (subaddress (12H), data (00)).
Set SW_52A and SW_53A to A.
Set to internal color difference input mode (subaddress (05H), data (80)).
Adjust the color data so that the amplitude of the R output pin (TP13) is 2 V_p-p.
Set to external color difference input mode (subaddress (05H), data (81)).
Measure the amplitude v_XIR of the R output pin (TP13) and calculate the amount of crosstalk.
XIER = 20Log ^{v XIR}

Repeat steps 4) to 7) above for the G and B axes and calculate the amount of crosstalk on those axes.
XIEG = 20Log ^{v XIG} XIEB = 20Log ^{v XIB}

Note 1: Where the bus data are not specified, set the preset value.
Note 2: Ensure the sync signal is always input to TP38 (SYNC IN).
