NanoVNASaver - jumbo77/NanoVNA GitHub Wiki
NanoVNASaver is developed by Rune B. Broberg. It is a multiplatform tool to save Touchstone files from the NanoVNA, sweep frequency spans in segments to gain more than 101 data points, and generally display and analyze the resulting data.
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)
Averaging data for better results particularly at higher frequencies
Displaying data on multiple chart types, such as Smith, LogMag, Phase and VSWR-charts, for both S11 and S21
Displaying markers, and the impedance, VSWR, Q, equivalent capacitance/inductance etc. at these locations
Displaying customizable frequency bands as reference, for example amateur radio bands
Exporting and importing 1-port and 2-port Touchstone files
TDR function (measurement of cable length)
Display of both an active and a reference trace
Live updates of data from the NanoVNA, including for multi-segment sweeps
In-application calibration, including compensation for non-ideal calibration standards
Customizable display options, including "dark mode"
Exporting images of plotted values
