1)
Set the subaddress (10) data to (20).
2)
Input signal 2 to pin 1.
3)
When the subaddress (07) data are:
(80)
γOFF
(82)
γ1ON
(84)
γ2ON
(86)
γ3ON
measure the changes in the amplitude level of the pin 43 output signal at
an increase the amplitude A of signal 2 and plot the characteristics.
4)
Calculate the
γON gradient , using Vγ, which represents the point at
which the
γ characteristics become effective, and the gradient of the linear
section with
γOFF as (1).

1)
Measure the voltage of pin 1.
2)
Set the subaddress (10) data to (20).
3)
Input signal 2 (picture period amplitude
= 0.4 Vp-p) to pin 80.
4)
Measure the picture period amplitude of the pin 11 output signal when the
subaddress (07) data are (80) and (81). (CLT0, CLT1)
