NanoVNA Frequently Asked Questions
Find answers to common questions regarding the NanoVNA V2 (S-A-A-2), VNA6000, and how to ensure you are using official hardware.
General & Hardware
What is the difference between the unbranded NanoVNAs and the V2 (S-A-A-2)?
The NanoVNA V2 (S-A-A-2) is a completely new hardware architecture designed by NanoRFE. Unlike the legacy V1 edy555 design which was limited to 300MHz (fundamental) or 900MHz (harmonics), the V2 uses dual ADF4350 4.4GHz synthesizers to achieve higher frequencies and better dynamic range.

How accurate is the NanoVNA compared to professional lab equipment?
For most amateur and hobbyist applications, the NanoVNA V2 performs exceptionally close to benchtop units. Independent comparisons by experts (such as DD1US) show that the V2 holds its own against professional VNAs like the HP-8753E.

Buying Guide & Avoiding Clones
How can I identify an official NanoVNA V2?
Official hardware produced by the developers is currently branded as V2 Plus4, V2 Plus4 Pro, and the VNA6000 series.
Warning on Clones: Unofficial variants like the LiteVNA, TinyVNA, SAA-2, and SAA-2N often use lower-quality shielding and components, resulting in significantly worse noise floors.
The following stores have a history of selling unauthorized or poor-performing clones: Banggood, R&L Electronics, Eleshop, and Nooelec.
Where is the safest place to buy?
We recommend buying directly from the NanoRFE Store or our Official Tindie Store. This ensures you receive authentic hardware with full developer support and the latest firmware.
