摘要

The DAB (Data Acquisition Board) is a key component of the VMPHA (Virtual Multi-channel Pulse Height Analyzer). In order to assist the design of the VMPHA, the influence of the DAB on the performances of the VMPHA has been studied through the method of theoretical analysis in this paper. The Sampling Rate,the LSB (Least Significant Bit) and the Data Transfer Rate of the DAB have decisive effects on the performance of the VMPHA. The Sampling Rate and the LSB are the two main factors that determine the energy resolution which is one of the most important performance indicators for the VMPHA. Another most important performance indicator for the VMPHA, the number of channels, is determined by the LSB alone. Moreover, the relationship among the three key performance parameters of the DAB is mutual influence. At the end of the paper, the selection method of the DAB for developing a VMPHA is summarized and presented.
