NanoVNA Witty Fox 3.7V 800mAh Li-ion GPS Battery power lines etcNanoVNA The NanoVNA is a compact, portable vector network analyzer (VNA) that measures S parameters, impedance, and transmission characteristics of RF circuits and components from 50 kHz to 900 MHz. RF engineers, hobbyists, and technicians use it for antenna tuning, filter design, PCB trace impedance verification, and component characterization without requiring expensive benchtop equipment. It solves the critical problem of real time RF circuit
