SnpParser.jl

A module for parsing and visualizing Touchstone files. Currently, only version 2.0 files are supported but there are ways to easily make version 1.0 files parsable by SnpParser.

Features

• Version 1.0 Support
• Version 2.0 Support
• Rectangular Plots
• Smith Chart Plots
• Parameter Conversion
• Mixed-mode parameters support

Usage

This assumes that you have a Touchstone file saved up in /path

julia> snp = TouchstoneSnP("/path/example_file")

julia> snp.parameter_type 
"S"

julia> plot_snp(snp, "S", "output.png", Set([[1, 1], [2, 2], [3, 3]]))

The output plot should look something similar to this:

Parsing version 1.0 Touchstone files

Version 1.0 is planned to be supported in a future release. However, there is an easy work-around by following the necessary steps:

• At the top of your Touchstone file add [Version] 2.0
• Right below the #options line add [Number of Ports] N where N is the number of ports. You can easily determine the number of ports from your network data: each row of your network data matrix should have N^2 + 1 columns
• Above your network data add the [Network Data] tag.
