Based on the increasing demands of high resolution video formats, and high data rates coming along with it, more and more interest is focused on transmission lines (connectors, cables) and their response to high frequency signals. Broadcasters are facing the challenge of making their studios, OB vans etc. future-proof with regards to HD1080p and thus would like to ensure that their equipment will provide reliable performance. Return Loss and Jitter are identified to be the key characteristics in judging compliance with high resolution standards.

We, Neutrik AG, as one of the leading manufacturers of BNC connectors, decided to accomodate the evolution of HD formats and to test our products with regards to the enhanced requirements. Theory on Return Loss and Timing Jitter
and corresponding measurement results are the basis of this paper.
