Timing adjustment
The position adjustment pane of the Levels/Position tab provides access to the following:
•
Horizontal position - output timing in 37ns steps
•
Vertical position - output timing in one line steps
Position adjustment controls (right hand pane)
Different horizontal and vertical timing adjustments can be maintained for 625 and 525
line operation.
The active output timing reference
The horizontal and vertical timing adjustments operate relative to one of two analogue
timing references. These are an external reference or an internal free-running clock.
When an external analogue timing reference is present serial output timing is maintained
relative to the external analogue reference.
When no external analogue timing reference present the serial output is timed to the free
running clock.
The following tables summarises the possible output timing reference sources:
