摘要
根据30MHz至1GHz电磁兼容测试场地归一化衰减(NSA)理论值的计算模型和公式,实现符合理想公式的不同条件下的各频率的NSA理论值的近似计算。同时利用NSA的计算结合笔者电磁兼容测试过程中的实践,对辐射发射测试中不同测试距离限值差异等三个实际问题进行了探讨分析。
The paper calculates the theoretical NSA of different frequency points according to the model and formula of theoretical normalized site attenuation（NSA） of Electromagnetic Compatibility test site in the frequency range 30MHz to 1000MHz approximately.Then analyzes and discusses the practical problem through the NAS calculation and the practical experience of EMC testing,such as the difference between the limits with different test distances in radiated emission test and so on.
