Python library for Touchstone .sNp parsing and S-parameter analysis in RF/microwave engineering.

touchstone.parser

Python library for Touchstone .sNp parsing and S‑parameter analysis in RF/microwave engineering.

touchstone.parser is a minimalist, polished, and community-friendly library designed for reproducibility and automation in RF/microwave workflows. It provides a clean API to parse .sNp files into structured Python objects with full support for NumPy.

Features

• Robust Parsing: Support for .s1p, .s2p, up to .sNp files.
• Full Metadata Support: Parses frequency units, parameter types (S, Y, Z, G, H), data formats (DB, MA, RI), and reference impedance.
• Scientific Integration: Direct conversion to NumPy arrays for easy analysis with SciPy and Matplotlib.
• Modular Design: Clean, type-hinted API designed for extensibility.

Installation

pip install touchstone.parser

Quickstart

from touchstone.parser import read_snp

# Load a 2-port Touchstone file
data = read_snp("measurements.s2p")

# Access frequency data (in Hz)
print(data.frequency)

# Access S-parameters as a NumPy array (shape: n_freq x 2 x 2)
print(data.s_parameters)

# Access magnitude and phase at a specific frequency
s21_mag = data.magnitude("S", 2, 1)
s21_phase = data.phase("S", 2, 1)
