Reference—Timing a PDR100
The PDR100 has a few special considerations that should be taken into account when
determining how to time your system.
• The PDR 100 is designed so that a prerecorded output is perfectly timed to the
Genlock Input, when no delay is set on the Video Output.
• Each type of input board has its own internal delay. (This should be compensated
for externally.)
• The PDR100’s Auto-Timing feature only has a pull-in range of
±
1 line.
