1. To pin 2, input a signal with a video component
amplitude of 50mVp-p and a sine wave (f = 100kHz)
with a sync amplitude of 143mVp-p.
2. Measure the pin 44 pedestal when the bright VR is at
maximum (VpdH).
3. Measure the pin 44 pedestal when the bright VR is at
minimum (VpdL).

1. To pin 2, input a signal with a video component
amplitude of 50mVp-p and a sine wave (f = 100kHz)
with a sync amplitude of 143mVp-p.
2. Adjust the bright VR so that the pin 44 pedestal is
0.95V ( = V44).
3. Measure the pin 43 pedestal V43 and the pin 45
pedestal V45, then calculate the following equations
using the values of V43 and V45.
Vof (B / G) = V43 V44
Vof (R / G) = V45 V44

3. Measure the pin 43 amplitude V43, the pin 44
amplitude V44, and the pin 45 amplitude V45, then
calculate the following equations using the values of
V43, V44, and V45.
Vdif (B / G) = 20og (V43 / V44)
Vdif (R / G) = 20og (V45 / V44)
