Ref Loop
The Reference Loop BNCs accept an Output timing reference signal. The
reference can be analog SD blackburst or HD tri-level sync. Examples of
permissible reference video input signals:
• 525 Color Black
• 625 Color Black
• 1080i Tri-level Sync
• 720p Tri-level Sync
The 2 BNCs are a passive loop: one BNC is for the Input, and the remaining BNC
can be connected to another piece of equipment in the reference chain or
terminated.
NOTE: For proper operation the input Reference signal must be stable and properly

terminated using a 75-ohm terminator on either the unused loop connector or
the last piece of downstream equipment to which the Ref Video is connected.
