Can you select the calibration from the popup in the Stimulus panel?

Yes
I can select a calibration file in the popup of the Stimulus panel
Delete selected calibration file remains grey in File Menu


Also
It will allow calibration files of the same name without warnings.

Okay, found it.

It will allow calibration files of the same name without warnings.

I will add a warning.

When you was able to calibrate, does this means all measurements are working? Your feedback is not very clear. Calibration is an option. It is not required since the NanoVNA gives us already calibrated data.
The 2.8" NanoVNA-H is limited to 1500 MHz and it is fixed to 101 scan points. I guess we need a feature so the user can change the limits.
