COUPLER
Loss-Free Loop-Out
of Video Data
Our Couplers were developed to loop out video signals of automotive video systems in real operation for analysis and recording. Their particular advantage lies in their passive mode of operation: This makes them independent of the installed technology, and reduces the impacts on connected components such as a camera, head unit or display to an absolute minimum, thereby guaranteeing signal integity. A signal sniffer can also be connected if the control channel data needs to be decoupled.
TZ Couplers are series-produced for the generally used GMSL and FPD-LINK technology standards. We will be pleased to realize other technologies and connectors individually for you on request.

Applications
- Monitoring and recording of video signals during real operation
- Recording of decoupled video signals during test and trial runs
- Hardware-in-the-loop tests (long-term tests)
TZ electronic systems offers a wide range of Couplers as standard. If your combination of requirements is not covered, then we are happy to implement a solution which meets your specific needs.

Functions
Our Couplers allow the simple and accurate decoupling of video signals – purely passive or partially active devices are available, depending on the task.
Purely Passive or Partially Active Function
Our purely passive Couplers are the prime choice for shorter cable lengths in the looped-out path. Partially active variants in which the looped-out signal is amplified and additionally duplicated are available for test setups where longer cables are required.
