Hi all, sorry not to be able to join the NGAUTO call yesterday as I am currently in Taiwan. I just reviewed the presented slides and I think this is very useful input. Thank you
all for generating this! One question remains to me: In Natalie’s presentation you showed that you need 4-port data (s4p) for differential cables in linear scaling. I assume this is mostly easily doable with a 4-port network
analyzer. Due to the also mentioned crosstalk I would like to know in which format this is needed? For crosstalk the setup would be a 8-port setup (if you e.g. use a shielded twisted
quad cable). Does this need to be measured also with phase the same time (means a s8p file)? I assume this to be a little bit difficult, as it would need a 8-port network analyzer… Or is for crosstalk also a separate measurement sufficient just measuring the cross talk alone (passive termination of the unused terminals) – or is it even fine to have
cross talk amplitude? Best Regards, Stefan Stefan Buntz Mercedes-Benz Cars Development, Daimler AG Group Research & Advanced Engineering Safeguarding Hard & Software

All – the ad hoc area now contains the presentations from this morning’s ad hoc meeting, as well as draft minutes and the meeting output confirming measurement formats and link segment measurements desired. Thank you
all for a productive morning, even if it was last minute. George Zimmerman, Ph.D. President & Principal CME Consulting, Inc. Experts in Advanced PHYsical Communications 310-920-3860 |
