A version 1.0 is surprisingly cheap, with a price tag of as little as USD $50 as of 2021, and yet it can reach up to 1.5 GHz. Preassembled units are available from at least one supplier in each of a number of places in Asia, Europe, and the USA. These machines are already used for educational, amatuer/ham radio, and applied engineering purposes. This article will compare a NanoVNA, or just the “Nano”, to a professional instrument.application/pdfenThis is an author’s accepted version of an article published in IEEE Microwave Magazine. © 2023 IEEE.Journal Article10.1109/MMM.2022.3233500
