I also have a nanoVNA-F with which I am very satisfied: use f < 300 MHz). Thanks to this forum I was able to update the Firmware. It is not essential but we can thus recover the .sp1 and .sp2 files produced by the box directly.
In reality I use my nanoVNA-F always connected to the nanovna-saver software which extends, with the notion of segment, the use of the box. I do a large part of the calculations from the .sp1 and .sp2 files produced by nanaovna-saver. It is good to set nanaovna-saver to produce a lot of measurement points. 2010 measurements is a bit slow but generally optimum.
Using nanovna-saver is quite easy. Remember to reset the CALIBRATE / RESET box each time before using nanovna-saver. It "normalizes" calibrations and measurements on the same basis.
If you are on Windows 10 or above, the standard version installs without problem. I'm on Seven and you need either a specific version or an old version.
