A (1) Apply 5 V from external power supply to pin 49.
(2) Set RGB CONTRAST to maximum (7F).
(3) Apply external power supply to pin 35. Gradually increase voltage from 3.0 V DC. When pin
43 output is clipped, measure picture period amplitude.
(4) Repeat step (3), making the following changes:
Input to pin 34 and measure pin 42 output; input to pin 33 and measure pin 41 output.
