解读1~40 GHz短距离设备电磁兼容欧洲标准
Interpretation on the European EMC Standard for SRD Operating
from 1 GHz to 40 GHz
摘要 对短距离设备(SRD)欧洲标准ETSI EN 300 440-1 V1.6.1进行解读,介绍了测试模型的选取、测试环境条件,同时较详尽地分析了发射机和接收机的参数要求,其中发射机参数主要包括有效全向辐射功率、工作带宽、杂散发射和占空比。接收机参数主要有临近信道选择性、阻塞性能和接收机杂散。此外,对传导和辐射测试场地和试验布置SRD设备中常用的几种频谱访问机制进行了概括说明。

Abstract This document interprets the European standard ETSI EN 300 440-1 V1.6.1.
What is included is the choice of model for testing, and test conditions. The transmitter
requirements (equivalent isotropically radiated power, permitted range of operating
frequencies, unwanted emission and duty cycle) and receiver requirements (adjacent
power selectivity,blocking,and spurious emission) are also explained comprehensively
Additionally, there are also illustrations on the test site and configuration of the
conducted and radiated measurements. In the final, the spectrum access technology
common used among the SRDs is introduced.
Keywords
short range devices, equivalent isotropically radiated power, spurious emission, duty
cycle
