Nano VNA like sand on the sea- Who is the "good one" ?

[Martin72]

Hi,

Update:
I have an attentive user here to thank for the fact that I can now call a cheap used Nano VNA my own.
I will look into it soon and keep this thread alive accordingly.
Thanks for all suggestions!

This specific model -F V2 I also have and it works fine...I think a better flavour of them.
There are updates etc. from Manufacturer Sysjoint

In the mean while I bought a LibreVna....another class price/spec but I keep the NanoVna for portable use on antenna/cables etc.

Good luck with it.

Can you post a link to that adapter set?
Did you measure it?

[Martin72]

Hi,

Adapterset

I haven't done anything yet, I wanted to finish two LCR reviews (ST42, ET3502) and finally get to grips with my scope (SDS3104X HD) before I start working on the VNA.
So it will take a while yet.

How does the LiteVNA64 stack up versus NanoVNA-F V3 that is a tad newer.?

If I recall, the LiteVNA64 uses 1x single MAX2871E synthesizer-chip or does it contain 2? while the NanoVNA-F V3 uses two 2x MAX2870 and a chip that are quite widely used-.

Though very common synthesizer chips, looking at their sheets, - Different revisions.

The V3 is a tad more expensive than the LiteVNA64
The LiteVNA seems to be spec with 10-1001 scan points, while V3 tops out at 801 points.
The V3 seems to have a higher screen resolution 4.3" 480x800 IPS screen? while LiteVNA64 uses 3.95" TFT 320x480 screen.
