根据电磁兼容检测标准中对待测物使用工况的要求,介绍了两种配合现有电磁兼容测量系统的辅助装置:低噪声工况信息记录仪和电磁兼容综合电参量测试仪。详细介绍了工况监测与控制仪器的设计原理,设计成功的该仪器引入极低的背景骚扰电平,完全满足相关测试标准对测试环境和测试系统配置的要求。对工况监测与控制装置在电磁兼容测试中的应用进行了详细分析,表明该装置可以应用在传导骚扰、骚扰功率和谐波电流发射测试。
According to the requirements of working conditions of the object to be tested in the EMC testing standards, two kinds of auxiliary devices are introduced in combination with the existing electromagnetic compatibility measuring system: a low noise working condition information recorder and an electromagnetic compatibility comprehensive electrical parameter tester. The design principle of the condition monitoring and control instrument is introduced in detail. The successful design of the instrument introduces a very low level of background disturbance and fully meets the requirements of the relevant test standards for the test environment and the test system configuration. The application of condition monitoring and control device in electromagnetic compatibility test is analyzed in detail, which shows that the device can be applied in conducted disturbances, harassing power and harmonic current emission testing.
