PDN means "power distribution networks", an odd term that had appeared for those low-Z nets of filtering MLCC caps in power rails, etc. )) All this nets are characterized by very low Z at low

You may try Walmart online, they have one that is close to the original for $20+ bucks.

PDN measurements? What does PDN stand for? I'd be careful about performance down lo

Hi nanoVNA users, This is my first post here so I hope I am posting in the right topic subgroup .. ? My reason for posting is that I am interested in buying and getting to know how to use a nanoVNA

discussion about VNA calibration error models: /g/nanovna-users/topic/34237712 This paper seems directly related to the Unknown Through Calibration error model, as I understand:

Hi, some related papers from net search, http://www.microwave.fr/publications/149.pdf There had been a discussion thread in this group with recent ly added related paper, too -- Alex

It's not mine but I do share the sentiment ;)

I've been retired for 18 years and even I DON'T have that much time, wow, I hope you have a day job. Very nice work though. Mike C.

Hi all, I am currently working on implementing various VNA calibration algorithms in MATLAB. I have succesfully implemented SOLT and one-port algorithms, but I am having trouble getting my head around

You needed to sweep up to a higher frequency to see your impedance null. A method to calculate the VF of any feedline, that will work with a VNA, antenna analyze or SWR bridge. (this sounds

Try to access the device using the serial terminal. Plug the device, find the serial port (type dmesg in the terminal, you will see a message at the end of the output) and use that in a serial

Alan, I wish to test a handful of collins 455 filters here. They are 2.1 wide. I see in your picture you are using some capacitors but cannot see the hookup. Could you please help me with the hookup

Hi Kevin, The real clue was in the Smith Chart plot you posted. I am really surprised that the Smith Chart gurus out there did not pick up on this straight away. My expertise with Smith Charts is very

I think it was because the OP said >> "How can I get it? I'm using c# and rs232 communication."<< Most of us read that as he wanted to do serial communication between the NanoVNA and the computer.

Bob, thanks so much for your very helpful response. I apologize to everyone in the group that's participated in this discussion that I haven't responded much or quickly. I didn't realize that what I
