The problem with the sweep was the port settings. If I set only the first one to the port for the VNA, then it would link but that was all. When I set the first two for the com port for the VNA, and it would link and sweep and do what would be expected, although I stopped for the day at that point before trying to do a cal.
Ok, that is a new one. I would never have tried to tell the software that the VNA and transfer relay are the same device. If it were actually a product, I think we would need to add a lot more protection for the users.
It makes no sense that the VNA wouldn't sweep if it links as the two ports are not related. I can add an enable for the transfer relay (pretty sure I had it at one time) if you feel that would make things less confusing. You would need to create a new defaults file to support it. I actually use the transfer relay from time-to-time and like not having to select it but am willing to change it.
Hopefully, everything for the crystal measurements will work.
"Works" has different meanings to different people. The last thing I bought from eBay "worked". Want to know how many hours and $$ it took to get it to "work" by the my definition (which is that it meets spec)?
Again the original $50 NanoVNA does a much better job of "working". For the LiteVNA, V2Plus/4 and suspect your Pro, narrow band measurements was an afterthought. The hardware was already set in stone with many poor choices and Dislord made an attempt to work around it in firmware. Maybe it will "work" well enough for you.
I exported an s2p touchstone file and that appears to have the s21 contained in it.
Guessing it does something but I doubt very much that it is correct. Maybe once you get a little further long, you can let me know.
BTW The leakage terms setting seems to fail to do anything noticeable in the measurements at the high end of the s21. Is that the proper place to look for it? Does that need to be saved into the configuration file before it becomes effective?
Well, I am not sure. You have told the software you have a transfer relay (which you don't), you then go through a full 2-port cal (which of course makes no sense as you don't have the hardware in place to do it). Then you attempt to collect some meaningful data. There are other things you could be doing as well that would effect the leakage corrections. It's also possible, but doubtful, that your VNA is so good, enabling it has no effect.
