(1) Apply 1Vp-p video signal as follows to video input.
(2) Measure the start point and amp gain of Black expansion at pin 19.

just
(1) TV Mode
:
Apply input signal 1 (f0 = 10kHz 0.5Vp-p) to pin 37.
External Mode
:
Apply input signal 1 (f0 = 10kHz 0.5Vp-p) to pin 39.
(2) Make pin 42 open. Adjust the data of sub-address (03) so that the output signal
amplitude at pin 21 become 0.5Vp-p.
(3) Measure the pedestal level at pin 21 when no luminance signal is input. (Y)
TCD = (Y / 0.5V)×100% [%]

Ad-
just
(1) Apply input signal 1 (20mVp-p) to pin 39.
(2) Set the data of sub-address (04) is (3F)
(3) Measure the output signal amplitude at B out when the signal (f0 = 10kHz) is
applied (V10K) and when the signal (f0 = 4MHz) is applied (VPK).
GSHMAX = 20og (VPK / V10K)
(4) Set the data of sub-address (04) is (00)
(5) Measure the output signal amplitude (VPK) at B output when the signal (f0 =
2.4MHz) is applied.
GSHMIN = 20og (VPK / V10K)
(6) Set the data of sub-address (04) is (20)
(7) Measure the output signal amplitude (VPK) at B output when the signal (f0 =
4.0MHz) is applied.
GSHCENT = 20og (VPK / V10K)
