解析401~402 MHz与405~406 MHz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
摘要 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,详尽地解读了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。

Abstract 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 .
