|30-07-2010||Current consumption has been measured, document is now available on the wiki.|
|30-07-2010||Changes for the second version of the PCB documented, mainly to solve thermal problems with regulators.
Required change of DC/DC converter and inductor.

For further information go to Investigating the distortion source...
|03-09-2010||Thermal stability measurements made.|
|03-09-2010||Frequency response of the anti-aliasing filter will be verified and possibly corrected.
Needs development of software that shows frequency response.
