Using the same tests as above, calculate BVn and RVn when the 5-V VCC is set to 5 V − 0.3 V
Input a rainbow signal (signal C-1) to the chroma input pin (TP45).Burst : chroma = 1 : 1
Gradually reduce the input signal amplitude from 100 mV
disappears (when the current is DC), measure the input signal amplitude v
Gradually increase the input signal amplitude from 0 mV
B-Y output pin (TP47), measure the input signal amplitude v
Perform the same tests as above while observing the bus read : When the input signal amplitude is v
check that the first bit is set to 0 (bCB).
