基于自动测试系统的ADC测试开发

A／D转换器（ADc）是混合信号系统中的重要模块，是电子器件中的关键器件。随着器件时钟频率的不断提高，如何高效、准确地测试ADc的动态参数和静态参数是当今ADc测试研究的重点。本文阐述了ADC的静态和动态参数测试，并在自动测试系统的ADC测试过程中，深入分析了ADC测试环境的配置，从而实现了一种低成本、高可靠性的ADC计算机辅助测试方法，并在BC3192VS0测试系统上得到了验证。

Testing development for ADC on automatic test system

Analog-to-digital converter(ADC)is the fundamental module in mixed signal system.As the clock-rate of the device is increasing continuously,accurate and effective measurement of ADC dynamic and static parameters becomes more and more important. The ADC static and dynamic parameter testings are introduced in this article. The ADC testing environment configuration is discussed in detail. A computer aided testing technique for ADC is presented, which is cost-effective and highly reliable. The proposed method was verified in BC3192V50 test system.
