Yes, saver has some bugs. In particular I have noted some inconsistencies
when trying to set it for 401 pts on the H4 (it works better if I let it
use 201 or 101 pts and then let Saver control additional segments for more
points).
Saver defaults to 101 points to maintain compatibility with older NanoVNA devices. I just go into Manage and set it to 401 points. Seems to work fine for me. What version of H4 firmware are you using? Which version of Saver?
But please note that many of us who use it want Saver to be in control, and
do not want to worry about what state their device was left in before they
attach it. And we do any required setup through Saver.
I think that is the best way to use Saver. Just power up the NanoVNA and use slot 0 so the same cal data is loaded every time. I keep slot 0 at 50 kHz. to 900 MHz. Then connect to Saver. That way when Saver calibrates it has the same NanoVNA configuration and you can reload the Saver calibrations at a later date. When I disconnect from Saver I power down/power up the NanoVNA because Saver leaves the NanoVNA in an unknown state. Saver supports multiple hardware versions of the NanoVNA and the software developers decided not to try and restore the NanoVNA to the state when it was initially connected.
You obviously have a different idea/use case. If you haven't tried
nanovna-app, you may find you like it better. In that app, you need to
understand that the many graphing and charting options are only seen after
right-clicking on a graph pane.
NanoVNA App by One-Of-Eleven is my preferred PC program for the NanoVNA. Better graph scaling and more features. I use the forked version by Owen Duffy because he fixed some bugs.
