Ok it looks like I need to do more work on the cal kit parameters. Previously the software only took S parameter files for cal kit definitions, and I've only added a "fine tune" UI which does length

Ken,I think you meant to say in the last paragraph that the MCU can NEVER be bricked as you will always be able to get back into dfu mode.? ... Larry On Fri, 24 Jan 2020 at 10:24 PM, Ken Liao,

Herb, Thank you for helping me test out the firmware. I was using Ubuntu and didn't try it out at Windows. I will be out of reach of my lab computer for the following two days. So it will take a few

Herb, How did you manage to get into DFU mode and reflash if the serial port was not recognized in Windows?

Ken, I used DFU File Manager to convert your hex file to dfu format and then DFU Demo (not File Manger as I previously wrote) was able to load the converted file without error. I encountered the

Ever wonder where the idea for this "RF Demo Kit" came from?? A company called MegiQ has been selling something similar for at least 4 years with their VNA.. https://www.megiq.com/products/vna-sandbox

Those new to VNA's will find this 3 part video tutorial very informative. It starts off with the basics, then moves on to calibration and finally on how to test components. Topics like using port

There's always the Wikipedia article, and its slew of references. https://en.wikipedia.org/wiki/Network_analyzer_(electrical) A VNA displays frequency, amplitude (impedance, return loss,

I ported Hugen's NanoVNA-H branch F303 to ChibiOS 18.2.2. This project only works for the new 4" LCD version, NanoVNA-H4. The project files are at https://github.com/AA6KL/NanoVNA-H4 You can download

Gabriel, I know you have been doing a lot of prototype testing in recent weeks to get more performance. Will the manufactured units have your latest changes in them or did you pass them a version from

Hi Gabriel Good idea including k0, k1 and k2 but yes there are more to it. The open has frequency dependent parameters normally represented by the C coefficients C0, C1, C2 and C3 which you may have

Hi Gyula - I suppose that is https://www.st.com/en/development-tools/stsw-link009.html .. which appears to be for ST-Link, NOT nanoVNAs.. Installing drivers from there may provoke a problem that we
