摘要:
A data acquisition system including a readout Application Specific Integrated Circuit (ASIC) having a plurality of channels, each channel having a time discriminating circuit and an energy discriminating circuit, wherein the ASIC is configured to receive a plurality of signals from a semiconductor radiation detector. The data acquisition system also includes a digital-to-analog converter (DAC) electrically coupled to the ASIC and configured to provide a reference signal to the ASIC used in the generation of digital outputs from the ASIC, and a controller electrically coupled to the ASIC and to the DAC, the controller configured to instruct the DAC to provide the reference signal to the ASIC.
