Symbol
Measure the DAC output voltage (Pin 20)
when BKG = 00/FF.
Input the crosshatch signal of Dot Clock
100MHz/ 0.7p-p to the RGB inputs, and
measure the VDET output amplitude.
VDET LEVEL = 0
Input a 10MHz sin wave to RGB at an
amplitude of 0.1Vp-p, and measure the
output level.

SHP1: SHP GAIN = F/SHP SW = 0
SHP2: SHP GAIN = 0/SHP SW = 3
SHP3: SHP GAIN = F/SHP SW = 3
Input 15 [IRE] and 60 [IRE] amplitude
signals (100 [IRE] = 0.7Vp-p) to the RGB
inputs, and measure the output amplitude.
