Is there any documentation on the formulas used by the NanoVNA to calibrate and correct measurements?


 

Hello,

I am looking for any references that explain the formulas used by the NanoVNA to do calibration and measurement corrections. I have looked at various six- and twelve- parameter corrections. Does the NanoVNA use these methods? I have looked at the DG8SAQ documentation and then derived my own method based on that. I am curious to how the calibration on the NanoVNA will be affected by various fixtures.

The calibration routines start at line 1034
