解析401～402MHz与405～406MHz短距离设备电磁兼容欧洲标准

Interpretation on the European EMC Standard for SRD Operating from 401 MHz to 402 MHz or from 405 MHz to 406 MHz

介绍了短距离设备欧洲标准ETSI EN 302 537-1 V1.1.2的测试条件、电源要求和环境要求,分析了辐射测试场地和测试布置。最后,详尽解读了401～402 MHz与405～406 MHz频段超低功耗医学设备的频率误差、发射带宽、有效辐射功率、杂散发射、低电压条件下的频率稳定度、基于低功率低占空比条件的频谱访问等发射机参数要求,以及接收机杂散的要求。

The European standard ETSI EN 302 537-1 V1.1.2 is interpreted from its requirements of test conditions,power source and the ambient temperatures.At the same time,there are also illustrations on the radiated test layout and test methods in the indoor test sites.Finally,in addition to the receiver requirements on receiver spurious radiation,the transmitter requirements are also explained comprehensively on frequency error,emission bandwidth,effective radiated power of the fundamental emission,unwanted emission,frequency stability under low voltage conditions and spectrum access based on low power and low duty cycle.
