A (1) Input signal 1 (f₀ = 100 kHz, picture period amplitude = 0.2 V_P-P) to pin 3.
(2) Change sub-address (0D) data to maximum (FE), center (80) and minimum (00), and
measure pin 42 picture period amplitude.
(3) Determine in decibels amplitude ratios of maximum and minimum to drive center (DRG_G1+,
DR_G1−).
(4) Repeat steps (1) to (3) above, changing sub-address (0E) data to instead, and determine in
decibels pin 41 picture period amplitude ratios (DR_B1+, DR_B2−).
(5) Repeat steps (1) to (3) above, changing sub-address (0E) data to center (81), and determine
in decibels pin 42 picture period amplitude ratios (DR_G2+, DR_G2−).
(6) Repeat steps (1) to (3) above, changing sub-address (0E) data to maximum (FF), center (81)
and minimum (01), and determine in decibels pin 41 amplitude ratios (DR_B2+, DR_B2−).
(7) Repeat steps (1) to (3) above, changing sub-address (0D) data to maximum (FF), center (81)
and minimum (01), and determine in decibels pin 43 amplitude ratios (DR_R1+, DR_R1−).
(8) Repeat steps (1) to (3) above, setting sub-address (0D) data to 81 and changing sub-address
(0E) data, and determine in decibels pin 41 picture period amplitude ratios (DR_B3+, DR_B3−).
(9) Repeat steps (1) to (3) above, setting sub-address (0E) data to 81 and changing sub-address
(0D) data to maximum (FF), center (81) and minimum (01), and determine in decibels pin 42
picture period amplitude ratios (DR_G3+, DR_G3−).
(10) Repeat steps (1) to (3) above, setting sub-address (0D) data to 81 and changing sub-address
(0E) data to maximum (FF), center (81) and minimum (01), and determine in decibels pin 43
picture period amplitude ratios (DR_R2+, DR_R2−).
