NanoVNASaver

A small tool to save touchstone files from the NanoVNA, and to allow sweeping frequency spans in sections to gain more than 101 data points.

Introduction

This software connects to a NanoVNA and extracts the data for display on a computer, and for saving to Touchstone files.

Current features:

• Reading data from a NanoVNA
• Splitting a frequency range into multiple segments to increase resolution (tried up to >10k points)
• Displaying data on Smith charts and logmag-charts for both S11 and S21
• Displaying two markers, and the impedance and VSWR (against 50 ohm) at these locations
• Exporting 1-port and 2-port Touchstone files
• TDR function (measurement of cable length)

Expected features:

• Mouse control of markers
• Further data readout for markers, such as return loss/forward gain
• Reading and displaying Touchstone files

Windows

The software was written in Python on Windows, using Pycharm, and the modules PyQT5, numpy and pyserial.

Linux

In order to run this app in Linux environment, you'll need the following packages:

• python3-serial
• python3-pyqt5
• numpy

To Run

python3 nanovna-saver.py
