道路车辆.窄带辐射的电磁能量产生的电干扰的部件试验方法.第7部分:直流射频(RF)能注入

[中文适用范围]： ISO 11452 的这一部分规定了直接射频功率注入测试，用于确定乘用车和商用车电子元件对窄带电磁能电气干扰的抗扰度，无论推进系统如何（例如火花点火发动机、柴油发动机、电动机） ）。 该测试方法涉及向 DUT（被测设备）提供差模激励，适用于除 RF 接地之外的所有 DUT 引线。 该方法适用于 0.25 MHz 至 500 MHz 的频率范围，可用于预测车辆环境中辐射和传导射频能量（包括传导瞬态射频能量）的兼容性，并且作为隔离手段特别有用DUT 内的敏感电路并评估潜在的解决方案。 [外文原描述]： ISO 11452-7:2003 specifies a direct RF power injection test for determining the immunity of electronic components of passenger cars and commercial vehicles to electrical disturbances from narrowband electromagnetic energy, regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The test method, which involves providing differential mode excitation to the DUT (device under test), is applicable to all DUT leads except RF Ground. Applicable over the frequency range 0,25 MHz to 500 MHz, the method can be used to predict the compatibility in the vehicle environment with respect to radiated and conducted RF energy, including conducted transient RF energy, and is especially useful as a means of isolating the susceptible circuits within a DUT and evaluating potential solutions.
