Touchstone.Parser Documentation

Welcome to the Touchstone.Parser API documentation.

This library provides a clean, modular, and enterprise-ready way to parse Touchstone (.sNp) files in .NET.

Getting Started

Install the package:

dotnet add package Touchstone.Parser

Then parse your first file:

using Touchstone.Parser.Parsing;
using Touchstone.Parser.Utilities;

var data = TouchstoneParser.Parse("filter.s2p");

foreach (var (freqHz, param) in data.GetS21())
{
    Console.WriteLine($"{freqHz / 1e9:F3} GHz → S21 = {param.MagnitudeDb:F2} dB");
}

For more details, see the README on GitHub.

Key Features

  • Parse .sNp files into strongly typed C# classes.
  • Multi-port support (1-port through N-port).
  • All data formats (RI, MA, DB).
  • All frequency units (Hz, kHz, MHz, GHz).
  • LINQ-friendly APIs for querying and transformations.
  • RF calculations (Insertion Loss, Return Loss, VSWR).
