The latest version of the NanoVNA just arrived.
The model is the NanoVNA V2Plus4. I features a 4 inch screen and it is supported by the NanoVNA-Saver program freely available.
This is a considerably improved version, capable of running up to 4.4GHz and displaying 400 test points on the built-in screen. The dynamic range is improved, too, with up to 80dB range up to 3GHz, when using 5x averaging, otherwise 70dB. Below 1GHz, and with 20x averaging all the way up to 90dB.
This makes this VNA very interesting as a stand-alone unit.
As with all the previous versions, this version can be used as a simple RF signal source, up to 4.4GHz.
There is always a catch. It appears that the people behind this design are working on a new version (v3) capable of measuring up to 6GHz. Not (yet) available, and probably more expensive, but probably worth it for me if I continue to want to build microwave equipment.
Now the question is, when will there be a version capable of measuring the 10GHz amateur band? It will not surprise me if we see a v4 with that capability in the not too far future (5 years?).
