This paper introduces the research and implementation of all-purpose high-speed test adapter for ADC. The main contents includes two methods about how to testing the static parameters and dynamic parameters for ADC. The servo loop method is proposed to static parameters, by using the test principle of high-precision voltage source, high-precision voltage meter and digital comparator. To dynamic parameters, the DDS chip of AD9851 is used to generate sine waves with high signal to noise ratio, then the high-s...
