(1) Input 50 Hz CVBS signal to Y2in.
(2) Change the input signal vertical frequency in 0.5 H steps and measure
the pull-in ranges fPL1 and fPH1.
(3) Set the sub address (04) D2 / D1 / D0 to (100) and measure fPL2 and
fPH2 same as in (2).
(4) Input 60 Hz CVBS signal to Y2in and set the sub address (04) D2 / D1 /
D0 to (001).
(5) Change the input signal vertical frequency in 0.5 H steps and measure
the pull-in ranges fPL3 and fPH3.
(6) Set the sub address (04) D2 / D1 / D0 to (101) and measure fPL4 and
fPH4 same as (5).
