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 :-)
