摘要
介绍了一种用于评价数据采集系统动态准确度的定义及测试方法，同时评价了其动态条件下的偏置误差、增益误差及模数转换有效位数，最终给出了一种数据采集系统的实际测试评价结果。
A method and definition to evaluate the dynamic accuracy of data acquisition system is introduced in this paper. By the curve fitting method, the effective bits, the errors of offset, the errors of gain are evaluated. The dynamic accuracy of data acquisition system is determined finally. Accuracy results using the method in test are given in the end.
