摘要
介绍了两种新的精确评价数据采集系统的直流增益和线性度的方法与过程，即“按码精确评价法”和“定间距（为量化误差整数倍）精确评价法”。同时讨论介绍了方法的优缺点及应用。
Two new evaluation methods and processes about the DC gain and linearity of data acquisition system are presented in this paper. They are 'precise evaluation on quantization steps' and ' precise evaluation on determining deviation between input-values'. At the same time the advantages,defects and application of these methods are introduced and discussed.
