Sorry everyone - I get that this is an annoying issue and would really like to solve it but I don't know where to start. No crashes or freezes on...

Hi TopQuark, many thanks for that, definitely interesting. I do not have a lot of experience analyzing these logs, but my first guess is a buffer overflow (due to all...

Thanks for the suggestions, I'll definitely keep them in mind. Here are some initial thoughts on the individual points: * ECP5: I never really bothered to check for other FPGAs...

Ok, I did not expect such a long and detailed comment, thank you so much for all your thoughts and ideas. I'll try do address most points: > I was...

> Since you mentioned some 10k points/sec sweep speed, are there any throughput concerns, in case of using ethernet? 100MBit Ethernet should be fine, it has more throughput capacity than...

> Except the usb, what other things are dedicated to the STM? The tasks of the different systems during a sweep are roughly like this: * STM: * Receives sweep...

>It might be a good idea to add RF gasket strips between the metal shields and the PCB all along the edges. I will definitely try to add the required...

If you look closely at the VNA from Henrik Forsten, you'll notice other similiarities (such as identical ICs in some positions). That design actually served as an inspiration for my...

Hi, thanks for taking an interest in the project, I hope this clarifies your questions: 1. Cost, mostly. A 40MSps ADC is significantly more expensive than the 1MSps I ended...

I am not too familiar with automatic code format checks, will look into it after next week
