Samtec’s Jim Nadolny (Samtec’s Signal Integrity and EMI Engineer), Keysight Technology’s OJ Danzy (Application Engineer), and Imagine Communications’ Boris Nevelev presented “Microwave Interconnect Testing For 12G SDI Applications.”
SMPTE ST 2082-1:2015 is the current standard for high speed digital video and requires testing to 12 GHz for video connectors.
Off the shelf test solutions exist for some types of cable connectors but are lacking for board mount video interconnect. A method to reliably de-embed PCB effects, bifurcate mated connector S-parameters and tradeoffs associated with the location of the 50-75 ohm transition is discussed in this paper and presentation.
The evolution of video signal bandwidth and the legacy issues surrounding video transport are addressed. The paper also discusses video broadcast trends and 12G SDI testing in particular. Method of testing connectors are explained, focusing on de-embedding of test board artifacts in a 75 ohm single-ended environment.
