1)
Input a ramp waveform to pin 78 and adjust the input amplitude so that the
picture period amplitude of pin 11 is 2.3 Vp-p.
2)
Adjust the drive adjustment data so that the picture period amplitudes of
pins 13 and 15 are equal to that of pin 11.
3)
Set the subaddress (14) data to (10).
4)
From pins 13, 15, and 11, calculate the RGB
γ start point and its gradient
(decibel conversion) in relation to the off point in accordance with Figure 2.

1)
Input signal 1 (f0 = 100 kHz, picture period amplitude = 0.2 Vp-p) to pin 78
and adjust the drive adjustment data so that the picture period amplitudes
of pins 13 and 15 are equal to that of pin 11.
2)
Apply 5 V from an external power supply to pin 27.
3)
Input signal 1 (f0 = 100 kHz, picture period amplitude = 0.2 Vp-p) to pin 22.
4)
Measure the picture period amplitude of pin 11. (V43R)
5)
As in steps 2) and 3) above, input to pin 24 and measure pin 13, then input
to pin 25 and measure pin 15. (V42G, V41B)
6)
GTXR = V43R/0.2
GTXG = V42G/0.2
