Thank you to Alexander Arsenovic, the original author of the OpenSource RF engineering Python library www.scikit-rf.org, for writing in and sharing with us a new program he has created called "tnt: [t]ouchstone [n]etworks in [t]erminals".

The program is written in Python, and allows a user to visualize Touchstone S-parameter graphs in a terminal, using simple ASCII character-based plotting techniques. Touchstone files are created by Vector Network Analyzers (VNAs), which are used to measure and tune antennas and RF components, or by RF simulation software.
