connector model for differential signalJohn:
Even and odd mode TDR analysis will give you a pretty good model for your connector.
You may want to check our application note on SCSI connector and cable characterization and the more generic appnote on differential line characterization, which can be found on www.tdasystems.com/support.htm. The appnotes discuss in detail characterization of differential lines in SCSI connector/cable assembly.

Subject: [SI-LIST] : connector model for differential signal
Dear SI gurus,
How to do connector modeling for differential signals, such as SCSI on a backplane?
Usually, I am used to use IPA510 modeling software with TDR to build a connector pin model.
The IPA510 will generate a Z-profile for the connector pin, create a RLC model, and then run spice simulation to verify model's accuracy. All mentioned above are for single connector pin. But, how about differential signals on the connector pins? What does the model look like?
Thanks for your comments in advance.
