电流参量测试仪及其在电磁兼容测试系统中的应用
Current Parameter Measurement Instrument and Its Applications in
Electromagnetic Compatibility Measurement Systems
摘要 介绍了一种新研制的电磁兼容测试系统辅助装置——电流参量测试仪。讨论了监测待测物使用工况的必要性,给出了电流参量测试仪的传导骚扰和骚扰功率的背景骚扰电平。该装置引入的背景骚扰电平很低,完全满足测试标准对环境噪声的要求。并使用某台式电脑主机进行测试,验证了配置电流参量测试仪的测试系统的有效性。

Abstract A current parameter measurement instrument as a novel auxiliary equipment
for electromagnetic compatibility (EMC) measurement is introduced.The paper discusses
the necessity of monitoring the operation condition of equipment under test(EUT).The
background noise level of this instrument under the condition of conducted disturbance
and disturbance power test is provided. This noise level generated by the instrument
is lower enough, so that the measurement circumstance could satisfy the requirement
of EMC standards. A table computer is used to test, and the corresponding results
demonstrate the good effectiveness of the instrument.
Keywords electromagnetic compatibility;conducted disturbance;disturbance power;
operation condition; auxiliary equipment
