Test Method
Input signal 1 (f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68.
Measure pins 12, 13, and 14 picture period amplitude, V₁₂, V₁₃, and V₁₄.
Calculate AC gain using the following equations.
G_R = V₁₂/0.2 G_G = V₁₃/0.2 G_B = V₁₄/0.2

2. Change unicolor data to maximum (7F), center (40), and minimum (00) and measure pin 12
picture period amplitude, V_uMAX, V_uCNT, and V_uMIN respectively.
3. Calculate amplitude ratio of V_uMAX and V_uMIN in decibels (∆V_u)
