ADC、DAC 静态特性测量标准

A Testing Standard for the Static Properties of ADC and DAC

本文介绍了我国ＡＤＣ、ＤＡＣ静态特性国家测量标准装置和它的测量技术。该标准装置通过多个ＣＰＵ和计算机，可以实现全自动测量并具有很小的微分线性误差、积分线性误差、零点误差和增益误差，实际测量速度为４０Ｈｚ～２５ｋＨｚ。在文章的最后给出了所达到的技术指标。

Abstract In this paper,a testing standard for the static properties of ADC and DAC and its measuring technology are introduced.By using several CPU and a computer,all of the measurements can be done automatically,and this standard has some advantages,such as high accuracy,small differential linearity error,small drift error and small gain error.The testing speed can be varied from 40 Hz to 25 kHz.The specification of the standard are also presented.
