Have you used libreVNA? It would be really nice to see a comparison of libreVNA and nanoVNA.

A nice review. I was impressed with my Nano VNA - an earlier model I think. To be honest the variations of NanoVNA are a bit confusing!

Does your R&S FPC1500 not outperform this at all frequency ranges? I'm surprised you needed one of these.

Thanks for the review. I love my NanoVNA. For a beginner in the RF world, it is amazing what it can show you. Someday, I may upgrade, but for now... these instruments are on par with my level of knowledge. [emoticon:fbd079a1c4f748c5a234faee215de9cc]

Looks like there are (at least) two different software sources which can be used!

One is in a github repo owned by a user hugen79, and the other is in a repo owned by user DiSlord.

It's actually very hard to tell which of these two are installed on the device. I had to search the source code!

In the NanoVNA device, tapping on Device->Version will display some info.

Mine contained the text:

Copyright NanoVNA.com 
based on  @DiSlord @edy555 ...source
Licensed under GPL.

According to a search of the source code, that's firmware built from the hugen79 repo content.

If it were from the DiSlord repo, then I ought to see the following text:

Copyright @DiSlord (based on @edy555 source)
Licensed under GPL.

So, similar-ish messages but subtly different! Anyway, I've concluded that the device came with hugen79 firmware, and in my case it's already at the current latest version.
