摘要
通过对元件进行阻抗频谱的测量,可以获取元件更有价值的数据。本文设计了以AD5933为核心的复阻抗频谱测试电路,简要介绍了测试流程及软件的编写,最后根据实际测试数据,对影响测量精度的因素进行了分析。本测试系统阻值范围为100Ω～10MΩ,能够满足一般阻抗频谱测试的要求。
More value data can be got by measuring impedance spectroscopy of component. Testing circuit of complex impedance Spectroscopy was designed based on AD5933. This paper briefly introduced testing process and designing of software. Finally influence factors of measurement accuracy were analyzed with actual measurement date. Resistance range of this testing System is 100Ω- 10MΩ.It can satisfy general measurement requirement of impedance spectroscopy.
