 (1) Input Signal a (horizontal period T = 35.56 µs) to pin 14 (HD3-IN).
(2) Set sub-address (02) 02.
(3) Set sub-address (00) 30.
(4) Input Signal C (vertical period initial T = 1ms) to pin 13 (VD3-IN). Increasing vertical period of Signal C,
measure the frequency FVPL0 when pin 28 (VD1-OUT) wave form synchronize with Signal C.
(5) Input Signal a (horizontal period T = 31.75 µs) to pin 14 (HD3-IN).
(6) Set sub-address (00) 70.
(7) Measure FVPL1 as well.
(8) Input Signal a (horizontal period T = 29.63 µs) to pin 14 (HD3-IN).
(9) Set sub-address (00) B0.
(10) Measure FVPL2 as well.
(11) Input Signal a (horizontal period T = 22.22 µs) to pin 14 (HD3-IN).
(12) Set sub-address (00) F0.
(13) Measure FVPL3 as well.
