(1) Short circuit pin 45 (Y1 IN) in AC coupling.
(2) Input synchronizing signal to pin 51.
(3) Connect power supply and an ammeter to the
APL of pin 44 as shown in the figure, and adjust
the power supply so that the ammeter reads 0
(zero).
(4) Raise the voltage at pin 44 by 0.1 V, and measure
the current (Iin) at that time.
Zo44 () = 0.1 V÷ Iin (A)

Vari-
able
(1) Set the bus data so that DC transmission factor correction gain is maximum.
(2) In the condition of the Note Y8, observe Y1out waveform at pin 37 and measure
voltage change in the video period.
(3) Set the bus data so that DC transmission factor correction gain is centered, and
measure voltage in the same manner as the above step 2
Adr = (V2 V1) ÷ 0.1 V ÷ Y1 gain

(1) Set the bus data so that black expansion is on and black expansion point is
maximum.
(2) Input TG7 sine wave signal whose frequency is 500 kHz and video amplitude is
0.1 V to pin 45 (Y1 IN).
(3) While impressing 1.0 V to pin 39 (Black Peak Hold), measure amplitude (Va) of
Y1out signal at pin 37.
(4) While impressing 3.5 V to pin 39 (Black Peak Hold), measure amplitude (Vb) of
Y1out signal at pin 37.
Akc = Va ÷ Vb
