A (1) Input signal 1 (f0 = 100 kHz, amplitude of picture period voltage = 0.2 VP-P) to pin 3.
(2) Measure pins 41, 42 and 43 picture period amplitudes V41, V42 and V43.
(3) Determine AC gain using the following formulae.
GR = V43/0.2 GG = V42/0.2 GB = V41/0.2

A (1) Input signal 1 (f0 = 100 kHz, amplitude of picture period voltage = 0.2 VP-P) to pin 3.
(2) Vary UNI-COLOR data to maximum (7F), center (40) and minimum (00), and measure pin 43
picture period amplitudes VuMAX, VuCNT and VuMIN.
(3) Determine amplitude ratio ∆Vu of VuMAX to VuCNT (in decibels).

A (1) Set SUB-CONTRAST to maximum.
(2) Apply external power supply to pin 3 and increase voltage from 5.8 V.
(3) When pin 43 picture period is clipped, measure pin 43 picture period amplitude voltage VWPS1.
(4) Repeat steps from (1) to (3) above (for VWPS2), changing sub-address (0C) data to 06.
