Users who compared clones using professional equipment found they do not meet specifications and are highly noisy. Unless you can compare your VNA to a professional VNA you will not be able to see that your measurements are off. V2/3GHz NanoVNA uses parts like Analog Devices ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
Beware of underperforming clonesĪs of 2023 there are many clones on the market that do not go through any quality control or the factory tuning required to get good accuracy with the V2 design. Project website: Buy Please support the original developers by buying the original version from the Tindie link above if possible. Please note - this forum is not for after-sales support - please use "Contact Seller" on the site you ordered from. The latest version, V2 Plus4, reaches > 90dB dynamic range (see comparisons on the website below).
Compared to earlier designs, V2 uses only the fundamental signal for measurements and achieves higher dynamic range. It is not based on ttrftech's V1 NanoVNA design but a new from scratch design using 2 ADF4350 to cover up to 4GHz and Si5351 to cover down to 50kHz. This is the official discussion forum/user group for the NanoVNA V2, which is a low cost 4GHz T/R VNA (vector network analyzer). Important: a clone seller is claiming credit for our design and running phony groups, please be aware that NanoRFE/HCXQS is the only supplier of authentic units, and this group (NanoVNAV2) is the only official NanoVNA V2 group.
