Some people like to learn by reading manuals and tutorial guides. Others prefer videos in order to learn how to use a NanoVNA. Many of the YouTube videos are poorly done and contain technical errors. You have to search for the gems.
However those done by W2AEW are consistently excellent and I have learned a lot by watching them. He covers many technical and ham radio topics but has quite a few on the NanoVNA. The videos are easy to watch, well edited and have clear, technically accurate content.
Here is a link to the site:
New VNA Users should start with #312 - What is a VNA. Then proceed to #313 on NanoVNA calibration and #314 on antenna measurements. The other videos cover NanoVNA topics like measuring crystal filters and filters, determine coax parameters and other interesting topics.
