A nanoVNA has a USB serial port. ?You can type commands into its serial interface to make the nanoVNA dump the frequency and IQ data from the last scan as plain text. ?See: ?
Maybe I do things the hard way; but I plug the nanoVNA into my Mac, open up a serial terminal app, command the nanoVNA to do a scan, dump the data, and use some simple scripts to reformat this text data into CSV files for spreadsheets, or "touchstone" files, or plot the data as either a Smith chart or an SWR graph.
