摘要
SFDR是评估ADC模数转换系统的重要指标,往往决定了数据采集和信号处理系统的整体性能,但在实际工程中很难得到准确的测量结果。其原因有对概念的理解问题、测试条件问题、算法问题以及测试技巧问题。总结了多年工程实践的经验,从多个方面分析了影响SFDR准确测量的因素,提出了解决的办法和技巧。根据提示,基本可以测量出满意的ADC模数转换系统的SFDR指标。
SFDR is an important index in evaluating the ADC module conversion system, often determines the overall perfurmance of the data acquisition and signal processing system, but it is difficult to get acc, urate 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 practiee, are analyzed from the aspects of muhiple 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 eonversion system.
