摘　　要：频域动态测试法是基于数字信号处理技术的高速模数转换器动态参数测试法之一,该方法能快速准确评估高速ADC的性能。利用PC、DSP芯片和FIFO芯片,设计和搭建了一套操作简易的高速ADC动态测试平台,完成了硬件设计以及相关测试软件编程,实现了对高速ADC9480(8位)的频域动态测试。该方法结合了MATLAB和串口通信两者优势,可以方便快捷地对ADC动态性能进行测试。测试结果表明该动态测试平台可行且操作简便。Frequency-field dynamic testing method based on digital signal processor is one of dynamic testing methods of high-speed analog-todigital converters. It can evaluate the performance of high-speed ADC accurately and quickly. A suit of high-speed ADC dynamic testing station based on PC, DSP, and FIFO is built that can be operated easily. Its hardware design and software program are fulfilled and realized dynamic testing to high-speed ADC that is ADC9480 （8 bits）. This method combines the virtue of Matlab with the serial port. Users can test the ADC dynamic performance easily. Testing result indicates the dynamic testing station is feasible and operated easily.
