Abstract: This paper proposes the accuracy of the data acquisition system including accuracy of the amplitude of the signal sample and the accuracy of the time sequence of the sampling control,and presents a design of program-controlled sampling by precise synchronous triggering and timing in multi-mode.The design may realize the sampling control by program,and solve the problem about precise synchronous triggering and timing in multi-mode triggering. It improves the accuracy of the time sequence of the sampling control in the data acquisition system,as a result, it ensures the benchmark for signal analysis.
