Agreed. It’s wonderful device for the money. I wonder how many total NanoVNAs, have been manufactured and how anyone I am 99.99% sure that the $17 are a scam. I bought one for $20 or so, but

Thank you. The 30 MHz lower end on frequency m would limit its usefulness to me. There are a *lot* of designs coming out for VNAs. The main work looks to be in the software - perhaps the reason

Some firmware versions, 0.2.0 to 0.2.2, could show some problems with repeated "sweep" commands with no or short delay between them. It should be fixed in 0.2.3, so maybe that's it? There were some

Have you tried inserting a USB 2.0 hub between nanoVNA and Linux PC?

Tomohiro, you have given me the most performance for the least cost of any electronic device that I can remember and I can't thank you enough. I wonder how many total NanoVNAs, have been manufactured

I am of course using nanovna-saver for serious measurements! Were it not for your excellent app the nanovna would be gathering dust in my desk drawer by now. I started this somewhat academic

You might want to check out this project http://hforsten.com/cheap-homemade-30-mhz-6-ghz-vector-network-analyzer.html as a starting point for a design with more bandwidth. Alas, the licenses are

I'm not trying to convert anyone, but is there any particular reason you're not using NanoVNA-Saver, which runs natively on Linux? :-) -- Rune / 5Q5R

Nanovnasharp will run on Linux Mint 19.2 using virtualbox, which emulates everything right down to the hardware, so it is possible to install a Windows kernel mode driver. Here's the steps... -

YES THIS LINK WORKS AND IS EXCELLENT. SO GO FOR IT. ALAN http://na.support.keysight.com/vnahelp/products.html

The current firmware has problems measuring above 900MHz. As example below a 1000 point scan of the "Open" In my home build VNA I found that increasing the IF could help reducing noise. As a test I

The NooElect ad mentions a case too but I don't see it pictured. Think I'll order one. You can never have too many nanoVNAs.

From the picture, this version is very similar to the version I made, obviously not from ttrftech (edy555), and they made some mistakes to the picture. There is a high probability of fraud, please be

I think it just means that they are the first to get "authorized" to sell for ttrftech which seems to be associated with edy555 the original designer. I have had good experiences with nooelec and

Unfortunately they only ship within the continental USA but they have a really nice selection at good prices.? On Sat, 12 Oct 2019 at 9:42 AM, Oristo<ormpoa@...> wrote: > Well at least

Folks might care more if firmware optionally supported replacing multi-function switch by e.g. rotary encoder with pushbutton https://www.mpja.com/10-10-19.asp?r=247156&s=30

Try to save 2 times in a row. I use this firmware on my two devices, it is used by my friend, there are no problems. Perhaps you are not using a reset during calibration.
