辐射发射测试系统的期间核查统计研究
Research on Intermediate Checking Statistics of Radiated Emission
Test System
摘要 研究了辐射发射测试系统的期间核查方法,即采取80%置信度的数据处理和统计方法,用于测试系统的期间核查及不同测试系统间的比对,兼顾了不同测试系统重复性和复现性差异,又使测试结果的准确性、可比性符合相应的性能要求,有利于日常监控和提高检测质量。经过许多EMC 实验室应用,效果良好。

Abstract An intermediate checking method was presented for EMI radiated emission
test system. The 80% confidence was set for data processing and statistical analysis,
which was used for comparison survey on intermediate checking or different test
systems.It gives consideration to repeatability and reproducibility deviation of different
test systems, and fulfills the general requirements of performance of test system with
the accuracy and comparability. This method is applicable for quality control.It was used
in many laboratories and got fair effects.
Keywords radiated emission; 80%confidence; intermediate checking; reference
