A data acquisition (DAQ) system based on oscilloscope was developed and evaluated for radiation detector. The dedicated LabVIEW program that perform the oscilloscope control and the data process was developed. Triggered events for each analog channel were acquired and the output signals were subsequently digitized and recorded for offline processing. Radiation pulse generation circuit was developed to evaluate the intrinsic characteristics of DAQ system. Energy linearity and energy resolution performances were assessed by voltage-peak channels and FWHM obtained from Gaussian fit, respectively. Radiation detector consists of LYSO and GAPD array. The 16 output signals were multiplexed by the RCD networks, and they were fed into the custom-made preamplifiers. Voltage-peak channels was linearly changed as a function of input voltage and the estimated coefficient of determination (R²) was 0.999. No considerable changes in voltage resolution were observed. All 16 crystals were clearly identifiable on the resulting flood image and the mean energy resolution was ~15.1%. This study demonstrated that it is feasible to develop the DAQ system based on oscilloscope and LabVIEW program for radiation detector and the proposed approach offers opportunities to build simple DAQ system in various radiation measurement field.
