Test Method
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68. Control drive
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Set subaddress (02) data to (40).
Measure voltage amplitude of pin-8 input signal in ACB insertion period.

2. Set subaddress (02) data to (40).
3. Measure pin 8 DC voltage in Vï½¥BLK period. (#8VBLK)
4. Apply the current externally to pin 8.
5. Measure DC voltage of pin 8 in Vï½¥BLK period when pin-12 picture period voltage begins to
be decreased. (#8VBLK+)
6. Apply current outward from pin 8.
7. Measure DC voltage of pin 8 in Vï½¥BLK period when pin-12 picture period voltage begins to
be increased. (#8VBLK−)
8. DIK_in+ = (#8VBLK+) − (#8VBLK)
DIK_in− = (#8VBLK−) + (#8VBLK)
