3G SDI Demonstration Kits
In an effort to help engineers in the broadcast video industry
get a leg up on the critical front end for 3G SDI, Samtec in
collaboration with Brioconcept Consulting and Gennum, has
developed a customized demonstration kit for 75Ω 3G protocol.
The demonstration kit is exceptionally accurate at measuring
3G SDI signal quality in the connector breakout regions. It
simulates the entire transmission line path from the BNCs
through the high speed interconnect (the Samtec HSEC8
Series Edge Rate™ connector) and the equalizers and cable
drivers on the active board.
This careful consideration of measuring 3G SDI signal
quality ensures that the breakout region and the PCB will not
significantly contribute to signal degradation.
The demonstration kit utilizes high quality Samtec SMA
connectors to launch signals to/from the system for performance
measurement. The True75™ BNC is also integrated into the
passive interface cards with all three typical orientations
represented: edge launch (BNC7T-J-P-HN-ST-EM1),
vertical mount (BNC7T-J-P-HN-ST-TH1), and right angle
(BNC7T-J-P-HN-RA-BH1).
