We designed and built a 16-channel NIM module acting as preliminary analog processing of the signals to be converted by sampling ADCs for the CHIMERA 4π multidetector digital pulse shape acquisition system. The main functions of the module are: i) a second order anti-aliasing filter with two programmable cutting frequencies, ii) a programmablegain amplifier to cope with the full dynamic range of the...
The digital pulse shape data acquisition (DAQ) system used by the large area telescopes of the 4pi-multidetector CHIMERA requires transferring large amount of data to the computer. This is necessary so that the same information can be extracted from the detector pulses as in previous analog based systems. To overcome this problem, we have used a sampling ADC-board equipped with two TigerSHARC digital...
