==== The strange thing ====
 
The PSD measurements with the 50 mV calibration signal seem to indicate that the technical noise is about of 1 fT/sqrtHz. But the largest response we can get from the magnetometer is 15 μV/fT. The ADC is 16 bit with ±10V inputs. So the resolution is 300 μV = 20 fT. How is this even possible?
