A (1) Input signal 1 (f₀ = 100 kHz, picture period amplitude = 0.2 V_P-P) to pin 3. Adjust DRIVE
GAIN 1/2 so that pin 41/42 picture period amplitude is equal to that of pin 43.
(2) Set sub-address (02) data to 40.
(3) Determine voltage amplitudes while ACB pulse is being applied to pin 45 input signal as
shown in Figure 1 of T19 above.
At 1H = IK_R, at 2H = IK_G and at 3H = IK_B

(2) Set sub-address (02) data to 40.
(3) Determine DC voltage of pin 45 during V-BLK (#45VBLK).
(4) Apply external voltage via 10 kΩ and gradually increase the voltage from 0 V.
(5) Determine DC voltage of pin 45 during V-BLK when picture period amplitude of pin 43 has
just started decreasing (#45VBLK+).
(6) Reset the external voltage to 0 V and gradually decrease from 0 V.
(7) Determine DC voltage of pin 45 during V-BLK when picture period amplitude of pin 43 has
just started increasing (#45VBLK−).
(8) DIK_in+ = (#45VBLK+) − (#45VBLK)
DIK_in− = (#45VBLK−) + (#45VBLK)

(2) Apply 5 V from external power supply to pin 49.
(3) Input signal 1 (f₀ = 100 kHz, picture period amplitude = 0.2 V_P-P) to pin 35.
(4) Measure picture period amplitude v43R on pin 43.
(5) Repeat steps (3) and (4), making the following changes.
Input signal 1 to pin 34 and measure pin 42 output (v42G).
Input signal 1 to pin 33 and measure pin 41 output (v41B).
(6) Calculate using the following formulae.
GTXR = v43R/0.2 GTXG = v42G/0.2 GTXB = v41B/0.2
