Hi All,

I find a very interesting project which I think is worth to share:

Project webpage: https://nanorfe.com/nanovna-v2.html
Discussion page on EEVBlog forum: https://www.eevblog.com/forum/testgear/nanovna-v2-aka-s-a-a-2/
Discussion page on groupsio: https://groups.io/g/NanoVNA-V2/topics

An improved version up to 6GHz: http://www.yl3akb.lv/content/vna_v2/vna_v2.php

hope this helps,

https://www.tindie.com/products/hcxqsgroup/nanovna-v2/

on the page it says there are many clones on Aliexpress and eBay.
Many of these perform poorly, can not meet the specifications,
and do not go through any quality control!!!

so take your pick...

For those who would prefer a PC-based VNA that is reasonbly-priced, please check this 4 GHz VNA:
https://pocketvna.com/
Still, its software is open-source.

https://pocketvna.com/

"High performance: up to 80 dB dynamic range in the MHz range; up to 40 dB in the GHz range
Broadband: 500 kHz to 4 GHz"

not a valid choice IMHO.

Current nanoVNA 2:
Frequency range: 50kHz - 3GHz
System dynamic range (calibrated): 70dB (up to 1.5GHz), 60dB (up to 3GHz)

there will be a 2nd nanoVNA revision in 2-3 months with more dynamic and less noise
