I am a current graduate student and am thinking of designing a sensor using microwave technology which requires S-parameters for calculations.
It would be a great way to use the NanoVNA instead of an expensive vector network analyser for real time data collection as well as calculations.
However, there is still a lot to learn and I only have a preliminary idea, so I need to reinforce my knowledge and ask here about the feasibility of this idea,

Good luck Yancy ,I'm not technically enough ,but sounds a great concept Dave

NanoVNA H and H4 use simple plain text serial communication so it's
feasible. V2 and
other variants are a bit more complicated but still nothing out of the ordinary.

I have not used an Alfred Vector Analyzer in decades.



These NanoVNAs are great for educational and hobby purposes; but contractually for engineering work they are N/A.



Good luck in your career as mine has been a blast from tubes to things in the DoD one cannot talk about.

NanoVNA use STM32, and open source, you can modify code and add all needed features. You can log data to sd card or on serial port or display on screen

With lot of caution - you could use nanoVNASaver  software as a
"base". The GUI is little cumbersome, for my taste, but the "math" is basically there .

And there's a variety of python libraries and code samples out there to
give you an semi-abstracted interface (I'd look at nanovna.py,
nanovna-saver, and nanovnacmd.py (which uses some of nanovna-saver.

The challenge you'll face is the limited sweep speed and data transfer.

I'd definitely look at the (somewhat out of date) list of the serial
commands. NanoVNA_Console_Commands_Dec 9-19.pdf and that will give you
an idea of how the interface works.

I don't know why you couldn't use a NanoVNA for contracted engineering
work. It's a matter of calibration, standards, and process - and
understanding the limits of performance. Gosh, people use a Simpson 260
professionally, and that's hardly a paragon of accuracy and performance.

why use another stm32 to display what the nano v2 can show??

i do not get the idea
