Abstract The structure with multi-ADC parallel sampling can rapidly increase the real-time sample rate of high speed data acquisition system.The whole diagram of a large-scale parallel sampling system is introduced. The technology of the generation of high speed parallel clock network, trigger point location and the real-time calibration of the non-uniform sampling are discussed. The experiment results are presented and analyzed. This high speed data acquiring system has the merits of low-cost, reliable performance and real-time.
