MEASUREMENT METHOD
C1
ACC Characteristics
B
ON
1) Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 1 : 1
2) When the chroma input amplitude levels are set to 10, 30, 300, and 600 mVp-p, measure the output amplitudes va10, va30,
va300, and va600 of the R-Y output pin (TP48).
3) Calculate A = va30 / va600.
C2
Color Difference Output
Level
B
ON
1) Input a rainbow signal (signal C-1) to the chroma input pin (TP45).
Burst : chroma = 300 mVp-p : 300 mVp-p
2) Change the burst phase so that bar 2 of the B-Y output pin (TP47) output waveform is the bottom peak and bar 7 is the top
peak.
3) Measure the amplitude (vB) of the B-Y output pin (TP47).
4) Set the burst phase to 180°.
5) Measure the amplitude (vR) of the R-Y output pin (TP48).
C3
Color Difference Output
Relative Amplitude
B
ON
1) Calculate the relative amplitude vRB from the following formula using the values obtained in steps 3) and 5) of C02 above.
vRB = vR / vB
1) Input a rainbow signal (C-1) to the chroma input pin (TP45).
Burst : chroma = 200 mVp-p : 200 mVp-p
2) Calculate the demodulation angles θBcnt and θRcnt of the B-Y output pin (TP47) and the R-Y output pin (TP48) using the
formulas and diagram below.

1) Calculate the relative phase θRB from the following formula using the values obtained in C04 above.
θRB = θRcnt θBcnt
Note 1: Where the bus data are not specified, set the preset values.
Note 2: Ensure the sync signal is always input to TP38 (SYNC IN).
