GB/T 33014.1-2016英文版/English/翻译
1 SCOPE
This part of GB/T 33014 specifies the general conditions, test instrumentation and test procedure for determining the immunity of electrical/electronic components (ESA) to electrical disturbances from continuous narrowband radiated electromagnetic energy.
This Part is applicable to the electrical/electronic components for Categories M, N, O and L vehicles, regardless of the vehicle propulsion system, e.g. spark-ignition engine, diesel engine and electric motor.
Note: The immunity testing set out in this series of standards is applicable to the continuous narrowband electromagnetic fields of which the frequency range is 0.01 MHz to 18,000 MHz.

4 试验条件
4. 1 一般规定
本系列标准中规定的试验方法、程序、试验仪器和等级是用来确定ESA 对窄带辐射电磁能引发的电骚扰的抗扰特性，为车辆制造商和零部件供应商之间的协议提供依据。
有些ESA 对电磁骚扰信号的一些特性（比如频率、严酷等级、耦合方式或调制类型等）非常敏感，有些则对调制射频信号比未调制信号更敏感，这是由于高频骚扰可能被半导体器件解调；未调制信号可能会导致电压等特性的持续偏移，而调幅信号被解调后产生的低频波动信号有可能被电子装置误认为是有用信号（如速度信息），此时被测装置CDUT）就更容易受到严重干扰。
单一试验方法可能无法反映DUT 抗扰性的全部信息。因此使用本系列标准时应预先确定合适的试验条件，选择GB/T 33014 的相应部分，定义DUT 的性能指标。每个试验方法的主要特性见表1.
