Reply To: S-parameter causality issue

Hi Dan,

Thanks for these pointers!  I was able to extract causal Z-parameters from both package and board designs using your suggestions.  For referenece, I am running Ansys 2023R2, and unselected compute exact DC point.

For my own educational benefit, what is your reasoning behind these sweep recommendations?  You double sweep select frequency regions, is that what helps to generate causal results?

Best,

Alex
