The only reason I was wanting to increase the frequency range was to increase the time domain resolution.   I wanted to use the PNA as a comparison to the $120 LiteVNA.  They limit the LiteVNA's firmware to 9.3GHz.   Attached are two of the circuits I demo'ed  (splitter with an LC tank and a low pass filter).   The data from the PNA is pretty much what I would expect.   

You can see the demo here if interested:

Finally got around to looking at the video. Very nice software... must have taken you a long time to develop. I hope the LiteVNA folks funded some of the development. LOL

I should have all the equipment on hand in the next week or so to run the alignment. Let me know if you want me to provide  any information.

joeqsmith:
Thanks.  The software started with my first VNA a few decades ago and continues to evolve.   It's self funded except for a friend had purchased the one of the LiteVNAs and my first NanoVNA for me to help them understand how to use a VNA.       

The suppliers have provided their products to some of the larger YT channels for reviews (unboxing).   I haven't received anything from them and have not asked.  Now if Keysight offered to set me up with some new equipment, I would be open for chat.   :-DD 

I'm basically stuck with the PNA.   If you decide to increase the frequency range, it would be interesting to see how level your source was before and after alignment.  The problem, I am not sure you can get that data without writing custom software for your setup.  It may help answer what to expect if I ever were able to align it.

If you have backed up your EEPROM like I show above and assuming you are aligning the source, it would be helpful if you backed up the EEPROM after alignment as well.  Then provide both files.  This will tell us if this is where they are storing this data and if so, which locations changed.

Ok... Will do.

I backed-up my EEPROM. It saved a eebud.dat file in D:/calfiles. It is quite a bit different than the original eebud.dat file that dates back to 2004. I then selected the restore EE data, which prompted me for a password (tsunami). I exited though without performing a restore. Did you get the "save EEPROM data" menu after following through with the restore? I can't get that menu to show up.
