SParamix

RF and microwave network parameter utilities for GNU Octave - a first(?) RF/microwave package for GNU Octave

Easy to use S-parameter quality checker, with IEEE 370 implementations

Python implementation of IEEE370 Octave code with calculation speed optimizations.

A free, open-source training kit for learning fixture de-embedding - a technique of Signal Integrity. This library provides synthesized and measured S-parameter files demonstrating de-embedding concepts, pitfalls, and best practices.
