Just tested previous firmware it works stable with 1 kHz span. Yes, it has wrong measurement with span below 100 Hz. But the new firmware is unstable below 10 kHz, this is much more worse...

Hi to everyone, About the nanovna2. I really dont mind the screen size. I have the first one and find it ok. The only thing is that if used outside it is low in lights. But the size, not a problem, I

Hello, Allow us, please, to summarize briefly: (0) The measurement uncertainty is error-bounds of the measurement. (1) If a measurement does not involve mathematical expressions then someone can

VNAs here going up to 20 GHz, building another is not high on my priority list. Perhaps if I was retired, it is something I would do. When I briefly showed the NanoVNA at my radio club, several

I saw his schematics and RF simulation files too when it was public repository. /g/nanovna-users/message/2148 Seems NanoVNA2 dev hiding his works...

As another way to isolate the source of the 1KHz peaks I ran a test where I adjusted the PLL i

I use a home build VNA for measurements above 900MHz so have no interest to buy anything else.

I suggest the ADF5355 also but it is much more expensive than the ADF4351 (especially if you need two of them)... https://www.analog.com/media/en/technical-documentation/data-sheets/ADF5355.pdf About

Indeed, thanks

If you want a really big screen you can easily build on yourself using very similar HW and some ebay modules. Two ADF4351 generators, a resistive bridge and some AIM81001 mixers dead bug style on a

Kurt, Allow me to share my T-check excel spreadsheet. Copy your 2 port touchstone data into the yellow cells and the graph will show the deviations Hope I did not make a mistake in the calculations.

Hello Erik, Thank you for adding your extension to the Hugen nanoVNA version 0.1.1. It would be nice to fill out in the "version window" the version number, e.g.: 0.1.1 + scan, 1500MHz It can be done

Hi David I got permission from R&S to publish their T-Check software http://www.hamcom.dk/VNWA/T-Check.zip and http://www.hamcom.dk/VNWA/T-Check_HD_Install.zip But that was in 2012 and now you just in

Hello, Mr. Kirkby, would it be possible to reduce your unnecessary lines to the essentials? It would increase the readability of your inflated messages...

Instead of the AD8342 I would suggest the type IAM81008 in the mixer stages. It is specified up to 5 GHz and has an easily solderable package. Wolfgang DH1AKF

Wow. What after that - a NanoVNA VNA version 3 with 4 receivers supporting unknown thru calibration? In all seriousness, I feel the biggest problem with the NanoVNA is the size of the screen. Dave --
