Digitiser Measurements

Noise measurements taken over time while changing the sensitivity of the digitiser:

This suggests a minimum measurable noise of 0.32 mV with the digitiser at its most sensitive and 190 units with the digitiser at its least sensitive which corresponds to 14 mV.

Preliminary measurements of the noise spectrum of the digitiser:
