Measurement methods
(1) Input 700mV(p-p) FVSM 2T pulse to pin61 (Y in).
(2) Set the BUS data of contrast to the maximum and increase
the BUS data of Sharpness from the minimum to a value
where pin14 (B OUT) waveform is not distorted.
(3) Measure the phase difference between the timing at the
center level of pin18(B OUT) and the timing at peak level of
pin18(VSM OUT) which responses the pin61 input., that is
TVMFP.
(4) In case that pin61 input signal is 2T pulse, the phase
difference is T

sine wave signal (see Y9) to pin61(Y
in).
(2) Apply dc voltage for pin15(Ysm) and increase the voltage
from 0V. Measure the power supply voltage when pin18(VSM
OUT) output disappears, that is V

(1) Input a 4.43MHz PAL rainbow color-bar (burst:chroma=1:1)
with sync into Pin61
(2) Set Tint to 64 and adjust the burst phase so that the 6th bar
of Pin14 output is maximum, that is
