About NanoVNA V2

NanoVNA V2 is a low cost 3GHz T/R vector network analyzer designed by HCXQS in collaboration with OwOComm. The V2 hardware is a new from-scratch design and is not based on the original NanoVNA by edy555. Compared to the original NanoVNA, V2 does not use harmonics for measurements and achieves higher dynamic range.


There are several manufacturers of the V2 and resellers on Aliexpress, Tindie, Taobao, and eBay. Performance varies.
