It's a common practice for RF, microwave and high speed design engineers to pre-process and validate the scattering parameters (S-parameters) reciprocity, passivity and causality before proceed to use it. This notebook will walk through a sample implementation in python to show a simple way of S-parameter manipulation and plot to provide a quick examination through visual inspection. It will cover the following steps:

• load a sample 4-port S-parameter file hosted on the Internet (load file through its URL)
• single-ended S-parameter to mixed-mode conversion
• Output magnitude in dB for specific measured frequency points of interest
• Insertion loss plot for report and visual inspection quality check purposes
