摘　　要：在进行汽车电子产品电磁发射(EMI)测试过程中,常规选择峰值检波器、平均值检波器和准峰值检波器进行相关测量,相关标准(例如CISPR 16、CISPR 25)中对接收机的参数设置也进行了规定,以保证测试结果的准确性和一致性。文章重点分析不同的干扰信号,针对不同的Measurement Time设置对峰值检波器和平均值检波器测试结果的影响,并给出相关建议。In the process of test of the electromagnetic emission(EMI)of automotive electronic products,peak detection,average detection and quasi-peak detection are selected for correlation measurement,parameter settings for the receiver are also specified in relevant standards(e.g.CISPR 16、CISPR 25)to ensure the accuracy and consistency of the test results.Based on the analysis of different interference signals,the influence of different Measurement Time settings on the test results of peak detection and average detection is discussed,and relevant suggestions are given.
