解析9 kHz~30 MHz短距离设备电磁兼容欧洲标准
Interpretation on the European EMC Standard for SRD Operating
from 9 kHz to 30 MHz
摘要 介绍短距离设备欧洲标准ETSI EN 300 330-1 V1.7.1的测试模型选择、测试条件、测试环境和电源要求,详细解读载波输出电平、工作频率范围、调制带宽和杂散发射等发射机参数和临近信道选择性、阻塞性能和杂散发射等接收机参数的要求。最后,对全电波暗室、半电波暗室和开阔场三种试验场地、试验布置和测试方法进行了详细说明。

Abstract The European standard ETSI EN 300 330-1 V1.7.1 is interpreted,including the
choice of model for testing, test condition,power source and ambient temperatures
Moreover, the transmitter (transmitter carrier output levels, permitted range of
operating frequencies, modulation bandwidth and spurious emission) and receiver
requirements (adjacent channel selectivity, blocking performance and spurious
radiation) are also explained comprehensively. Finally, there are also illustration on
the test layout and methods in the anechoic chamber, semi anechoic chamber and
open area test sites.
