When I first started out looking at the NanoVNA, there wasn't any open source software, thus my little attempt at a simple Python app. Has this software been made open source? Or is it simply modded

I think I'll just run mine on a USB Battery Bank. Sounds like less problems, longer life, and less chance of leakage, explosion etc ruining the device.

I have an early nanovna, I think - no shields and no silkscreen for Ch0. Trying to send back, as no S21 measurement, just noise. I tried updating firmware, using the STM app. When choosing dfu file, I

Dr. Kirkby, Excellent suggestion. Especially, for myself, the beginners section. Thank you. Regards, James Douglass Garden City, Kansas USA

Hello Ralph, You could also omit the "-d 0483:df11" parameter from the dfu-util command line. Ralph Thank you for the hint, but see the man page: -d, --device [Run-Time VENDOR]:[Run-Time

And here I am adding to the noise. But! the daily digest works! A bit late on some announcements, perhaps, but I can catch up. I'm not in that big of a hurry. I get to see a SUMMARY of all the posts

Been there. done that. This is my combined 3GHz VNA and 2GHz SA with TG Problem with this setup is the minimum VNA frequency of 35MHz due to the re-use of the two ADF4351 modules. The nanoVNA solves

If you search this forum, you will find messages about the limited life of the very small RF connectors on this board.

Hello Norbert, Thank you very much! :-) The "span" value is the -3 dB bandwidth - assuming the -3 dB points get placed correctly. The setup currently analyses as follows: 1) From the marker 1

If I can say a little something about this Idea. A tracking generator would not cost a lot more in ressources and would be a nice addon in a NanoSa. And the possibility to add an amplifier to the TG

Yes, it would be very useful. But could one go further and combine the SA & VNA into one unit? For what it is worth, Keysight sell a range of portable FieldFox instruments. They are either * Spectrum

Years ago, an otherwise knowledgeable ham and I had a public argument about the phase shift and delay through a 75m mobile antenna loading coil. Those conclusions are still posted on his web page -

Warren, Where can I purchase the 1-3000 MHz RF bridges? Thanks, Mike N2MS

Been looking at this lab card, and I wonder what is it useful for? I must not get it.. Is it a way to test our NanoVNA?

Rudi, You could also omit the "-d 0483:df11" parameter from the dfu-util command line. Ralph

While described as 101 fixed steps, fewer are evidently used by nanoVNA firmware for small spans. Given Si5351 setting granularity for artifact-free switching, what are rule-of-thumb minimum frequency

Hi Rune, first impression is outstanding! If you take a look at the BP-Filter I can't find the value of the width for the bandpass in respect to the -3dB points. Same for the -6dB BW. LP&HP analysis

Thanks for playing with this idea, Erik. There was a comment from a Japanese NanoVNA user on Twitter comparing the use of the Nano to an oscilloscope that is in the same price range but has poor
