NanoVNA Very tiny handheld Vector Network Analyzer User Guide 2019-05-27 Overview ： we designed NanoVNA based on edy555 (/edy555), but modified some circuits, added battery management circuits, and redesigned the PCB. The PC control software can export Touchstone (snp) files which can be used for various radio design and simulation software. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50k-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic. The extended 300M-600MHz band provides better than 50dB of dynamics, and the 600M-900M band is better than 40dB of dynamics. is very tiny handheld Vector Network Analyzer (VNA). It is standalone with lcd display, portable device with battery. This project aim to provide an RF gadget but useful instrument for enthusiast. DIYs vector network analyzer, with reference to the related design of, Designed with simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software. NanoVNA is an open source hardware project, everyone can be free to clone and DIY, but we hope you can do more understanding before you do it, there are some customers reflected that they have bought the low quality nanoVNA from other sources.We have found some low quality clones on the Internet which claimed have completed the project. Buying such hardware may be harm on NanoVNA performance
