Measurement methods
(1) Set the BUS data of Parabola correction to 0(MAX),and
change the BUS data of Trapezium correction so that the
parabola waveform at pin33(EW OUT) is symmetrical.
(2) Supply 1V into pin28(EHT in).
(3) Set the BUS data of H.EHT to 0.
(4) Measure the vertical phase center voltage of waveform at
pin33(EW OUT),that is V
EHD
(0).
(5) Set the BUS data of H.EHT to 7.
(6) Measure the vertical phase center voltage of waveform at
pin33(EW OUT),that is V
EHD
(7).

H-Parallelogram Correction
(1) Input CVBS signals with 10MHz of sin wave for
#61(CVBS1in)
(2) Set the IICBUS of 'Nose Det Level' to 3
(3) Measure the input sin wave amplitude at the level which
the Read bus of NOISE det turned to 1, that is 1VNDET3.
(4) Set the IICBUS of 'Nose Det Level' to 15
(5) Measure the same way as (3), that is 1VNDET3.
