Input RAMP waveform from pin 68. Adjust input amplitude so that picture period amplitude of
pin 12 is 2.3 Vp-p.
Set subaddress (0C) data to (81).
Adjust input amplitude so that picture period amplitude of pin 12 is 2.3 Vp-p.
Monitor pin 12. According to the figure below, determine Y-OUT γ correction start points γ1
and γ2. Also determine ratios of gradients at Y-OUT ON to Y-OUT OFF in decibel. (∆1, ∆2,
and ∆3)
