Design of High-speed Data Acquisition System Based on DRS4 Waveform Digitization

The high sampling rate, multi-parameter measurement, long distance transmission and so on are required in some particle physics experiments. In order to meet these requirements, a high-speed data acquisition system based on DRS4 waveform digitization was designed. The system consists of waveform digitalization front-end circuit, high-speed data transmission circuit and upper computer software. The test result shows that the system has the features of very high data transmission rate and low bit error rate. The input signal waveform can be well rebuilt and restored using the sampled data. This high-speed data acquisition system has the certain versatility, and it can be applied to particle physics experiment with higher requirement of high sampling rate and long distance transmission.
