Update (2023): we have now seen clones that display a false lower noise floor when measured value is below a threshold, which allows a higher dynamic range to be advertised but can introduce measurement errors. Beware that many exaggerate their specs, and some variants are highly noisy due to using incorrect or lower quality parts. If you are looking for a higher end offering, please check out our recently launched VNA6000 series.Īs of May 2023 there are many clones of our earlier S-A-A-2 design sold under various names. We'd like to thank you for choosing to support us by buying the original version! You are probably aware of the components shortage situation everyone is in right now, with many small businesses struggling to survive, as well as the flood of low quality clones becoming a major issue.
Safe places to buy an original NanoVNA V2: Cost of components are still rising, so prices may need to be adjusted in the future. Update: V2 Plus4 versions now available for order: although the components shortage is worsening (original parts are harder to find as low quality counterfeits flood the market), we have finally secured enough ICs for another batch of NanoVNA V2 Plus4s, now available for order from our official Tindie store.
Improved USB protocol allows full speed streaming of measured data to the PC.
TDR / Time Domain measurements allow testing cable length and discontinuities.S parameters export, custom calibration kit parameters & advanced calibration methods (NanoVNA-QT software).No noticeable drift, allowing calibrations to be kept for > 3 months (compared to 90dB, achieving similar results as professional VNAs, and allows measuring duplexers.The main improvements in NanoRFE's NanoVNAs are: The wide frequency range covers common cellular, Wi-Fi, and IoT bands, as well as HF, VHF, and UHF amateur radio bands. It uses our new VNA-R architecture featuring temperature drift cancellation and reduced crosstalk, showing no visible drift in all indoor conditions.Ĭompared to other NanoVNA versions, V2 Plus4/Plus4 Pro do not use harmonics for measurements, improving performance significantly, achieving 90% less trace noise, and is the only low cost VNA to give you highly repeatable and reliable measurements comparable to professional instruments. V2 Plus4 is the latest design which fixes the drift and linearity issues with older versions. It is a new from-scratch design by HCXQS/NanoRFE not based on the earlier edy555 V1 design. NanoVNA V2 (S-A-A-2) is a 4GHz vector network analyzer (VNA) capable of measuring antennas, filters, duplexers, and amplifiers.
