Hello All. I have a NanoVNA H-4, and I have been using DiSlord's 1.45 SW for about 9 months.
It is great,. it's stable and performed as expected.
I recently discovered the new 1.50 SW and decided to upgrade as it '"'faster" .
So, I upgraded to the new 1.50 SW revision, it loaded just fine, and calibrated etc as usual.
My problem however is odd, I wanted to test a 25MHz Elliptic LPF, using the S21 mode and LogMag. I use this mode often.
the problem is that I see nothing measured... just low level noise at -80dBm... Its almost like the RF sweep is not working to be measured.
I reloaded 1.50 and see the same thing. I then reverted to the older 1.45 SW and normal operation is resumed. My filter looks good.
I cannot find any menu mode to "turn" on the Sweep; is this a bug, or is there some extra mode or menu option I have not yet found to test S21 / LogMag?
I'd appreciate any suggestions.
Thanks!
Steve Mahrer
