SUMMARY
The discussion focuses on the mathematical theory and practical calculation of crosstalk parameters using S-parameters obtained from Vector Network Analyzer (VNA) measurements. Key crosstalk metrics include Integrated Crosstalk Noise (ICN), Power Sum Crosstalk (PSXT), Multi Distributed Near-End Crosstalk (MDNEXT), and Normalized MDNEXT. The user seeks exact mathematical derivations and code implementations to compute these metrics from S-parameters, referencing the OIF CEI 03.1 standard and Lamsimenterprises technical blog as authoritative sources. The conversation clarifies the interpretation of S-parameter terms such as S31, S51, and S71 for victim and aggressor lines and highlights the frequency range of 0.01 GHz to 67 GHz for simulation.
