SETTING PARAMETERS FOR COMPOSITE SYNCHRONISM AND FOR THE
HORIZONTAL
1
AND VERTICAL
2
PULSES
[M] COMPOSITE SYNCHRONISM
Selection of positive composite synchronism ( CS + ) or negative ( CS - ).
[N] HORIZONTAL SYNCHRONISM
Selects the positive horizontal synchronism ( Sync H + ) or the negative one ( Sync H - ).
[O] VERTICAL SYNCHRONISM

1
HORIZONTAL PULSE: The rise edge for the horizontal pulse appears 0.8 μ s before the
beginning of the horizontal synchronism and the duration of the horizontal pulse is 7.2 μ s.
2
VERTICAL PULSE: Is triggered with the vertical synchronism pulse, has 10 line periods of
duration in systems of 625 lines and 6 line periods in systems of 525 lines.
