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
