SFDR is an important index in evaluating the ADC module conversion system, often determines the overall performance of the data acquisition and signal processing system , but it is difficult to get accurate measurement results in the practical engineering. The reasons are for the understanding of the concept of the algorithm, test conditions, and test techniques. Summarizing many years experience of en-gineering practice, are analyzed from the aspects of multiple factors influencing SFDR accurate measurement, which puts forward the solution and skill. According to this article, we can basicly measure the satisfactory SFDR indicator of ADC modulus conversion system.
