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.
