This library is work in progress
This is a small library that allows to access the NanoVNA v2 vector network
analyzer using Python. It implements the VectorNetworkAnalyzer
base class of pylabdevs (since this
is work in progress there is currently an unfinished copy in this repository).
The nanovnav2fetch is a very simple command line utility that
allows one to fetch the S00 and S01 parameters as well as phases
from the NanoVNA v2. Note that this utility always depends on numpy (>= 1.25)
and requires matplotlib (>= 3.8.0) to plot or show the traces.
Those dependencies are not contained in setup.cfg since the remaining
library is not depending on these.
