Design of a Data Acquisition Module Based on PXI for Waveform Digitization
The waveform digitization is more and more popular for readout electronics in the particle and nuclear physics experiment. A data acquisition module for waveform digitization is investigated in this paper. The module is designed on a 3U PXI (PCI eXtensions for Instrumentation) shelf, which can manage the measurement of two channels of waveform digitization for detector signals. It is equipped with a two channels analog to digital converter (ADC) of 12 bits resolution and up to 1.8 G samples per second (SPS) sampling rate, and a filed programming gate array (FPGA) for controlling and data buffering. Meanwhile, a complex programmable logic device (CPLD) is employed to implement the PXI interface communication via PXI Bus. The performance of this module was tested. The results show that it can be successfully used in particle and nuclear physics experiments.
