Rune,
Just a note for any Fedora users out there. The right click to save an
image does not work under Wayland. I had to switch back to standard
gnome.
I also had an issue with the fonts in the marker area not using what
the rest of the screen was set to. I went back to 1.5 for now.
The software is great and I really appreciate all you efforts.

Hello Karsten,
The software takes readings from the NanoVNA, and displays them and
does
calculations on them. The readings taken are the S-parameters, S11
and S21,
so any settings for traces on the device are ignored. NanoVNA-Saver
does
its own calculations of derived values, including TDR. It allows
reading
more than 101 points by stitching together multiple "segments" of the
total
span of interest.
Calibration is available on the PC-side in NanoVNA-Saver, which
allows you
to get a calibration with more points than on the device itself, as
well as
the ability to use custom calibration standard sets.
The application does not (currently) support taking screenshots of
the
NanoVNA - there are excellent scripts that do this out there - but
you can
save images of any of the graphs via the right click menu.
Frequency generation is still fundamentally part of the firmware -
NanoVNA-Saver tells the firmware the start and stop frequency of the
"segment" it is currently reading, and gets back a list of the actual
frequencies read, and the values at those frequencies. To get a step
size
lower than 100Hz, you would need a firmware that supports steps of
that
size.
The software does not need a specific firmware, but newer firmwares
have
bugfixes, and I recommend using a new firmware to get the best
experience
with your device in general.
I hope I've answered your questions, otherwise, don't hesitate to ask
here
on the list :-)
