摘要
为测试电子产品电磁兼容性,基于MSP430单片机设计一种空间立体电磁干扰仪,提供多角度、多方位、多波段干扰源。设计中在带宽、频率一致性、信号完整性、制作工艺、调试精度等方面进行了深入研究,电路设计尽量采用功能芯片,提高整机的集成度和性能。
The three-dimensional space electromagnetic interference instrument based on MSP430 SCM is introduced which can provide multi-angle,multi-faceted,multi-band interference source for electromagnetic compatibility testing of electronic products.Several aspects include coherence bandwidth,frequency coherence,signal integrity,production process and testing precision in the design are studied.The circuit design used functional chip to improve performance and integration.
