Re: NanoVNA V2
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

Re: NanoVNA V2
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

Re: on the comparisons
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.

Re: Firmware summary
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

Re: on the comparisons
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...

Re: NanoVNA V2
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

Re: NanoVNA V2
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 --

Re: NanoVNA V2
I think that the adf4351 would be better: Main improvements compared to the ADF4350: * Improved 1/f in-band phase noise (5 dB) * EVM improvement of up to 30% * Lower PFD spurs * Wider output range: 35

Re: Evaluating clamp on ferrite chokes
Very kind of you to offer Kurt. I was an EMC project manager up until I retired, so I know how pressing deadlines are. I have time now-a-days to follow my whims and will mock up a few test set-ups on

Re: on the comparisons
I think this promises to be a very interesting thread. I spent my career solving wave equation problems. In my case, elastic rather than electromagnetic, the impedance is pure real. But the change to

NanoVNA V2
I gleaned the following information from one of the other nanoVNA user groups regarding nanoVNA version 2. 1. The nanoVNA will eventually reach 3GHz (and at a similar price to version 1). 2. It's

Re: Evaluating clamp on ferrite chokes
Hi Herb I did notice you already had mentioned part 2 and 3 "plowing" thru the next messages. Well I need to have a relatively low profile as I am in the midst of a huge project so only limited time.

Thanks for the heads up Kurt. I linked to parts 2 & 3 in a subsequent reply. I found the whole series of articles to be interesting reading and hope to construct a similar Test fixture for sorting my

Did you check it with the new nanoVNA-F? Its general parameters seem to be better by 10dB.
