The CSA board take care of analogic signal coming from the detector. It amplifies the low level sygnal and subtract the DC level (BIAS). This part is a simple part which require a lot of care and triks. |
The ASD board take care of converting the digital clocks coming from the SVB and converting to the appropriate voltage levels for the detectors. It also generates the DC polarization voltages required by detection stage. |
