NanoVNA: Can You live without One?

摘要

I'm looking at the NanoVNA, Fig. 1, a Vector Network Analyser. Vector Network Analysers are used to test components or combinations of com-ponents (networks) by measuring ampli-tude, phase and reflection characteristics. Typically, it might be used to verify design simulations to ensure that different stages are matched in terms of impedance. In the amateur radio world the two most common uses would be antenna and filter testing.
