What can I do with a Nano VNA?
If you are up to it - here is Part II of my ¡°Nano VNA¡± talk to the MidAtlantic ARC in May 2021 at their monthly Zoom meeting. The first 30 minutes or so is their Business Meeting - so skip ahead.
Part I Nano VNA The Basics was the previous month, April 2021 - almost no math.
Looking at the Nano VNA like one more ¡°tool¡± in your tool box.
Part II (a look under the hood) I was not afraid to get deeper into the weeds - logs and return loss in dB and Smith Charts plotting resistance and reactance in POLAR form.
I did make TWO errors - see if you can spot them.
The Nano VNA device is rather remarkable. A fantastic tool for about $100 now.
Mine is almost three years old now - an original from Amazon with the SMA connectors.
Take the time to learn what a VNA can measure and compute.
Again I used Windows Nano VNA SAVER software (free) to produce these graphs.
Best wishes
