摘要
汽车电磁辐射抗扰度标准GB/T17619-1998中对试验信号的要求与基础标准GB/T17626.3-1998的要求存在较大差异,这种差异对试验结果有很大影响。从标准理解、理论计算、实际测量等多个角度对其进行了分析和对比,以帮助试验人员在实际测试时正确地理解和调制试验信号。
Test result was influenced by differences of test signal between GB/T 17619-1998 and GB/T 17626.3-1998. Analysis and comparison was made in this article in view of standard understanding, theory calculation and actual measurement in order to accurately understand and modulate test signal.
