摘要
为研究电磁兼容测试中,布线方式对信息技术设备的辐射骚扰场强的影响,以典型信息技术设备为切入点,在视频线、音频线、键盘线、鼠标线与USB线的不同布线方式下,采用在电波暗室中进行实验的方法,对信息技术设备的辐射骚扰场强进行了测试分析,验证了辐射测试中线缆应遵循的布线原则,评估了不同布线方式对辐射骚扰场强测试结果的影响.研究结果表明:布线方式的规范程度将对信息技术设备的辐射骚扰场强测试产生不可忽视的影响,很可能影响测试结果的判定,主要是对低频段测试结果的影响.该研究结论对电磁兼容领域的辐射骚扰测试具有一定的参考价值和指导意义.
To research about the influence of wiring method on the radiated emission measurement of information technology equipment, this study took the information technology equipment as the example, conducted a series of radio emission tests in the anechoic chamber under the different wiring methods of video wire, audio wire, keyboard wire, mouse wire and USB wire, and verified the wiring principles during the radiated emission measurement and evaluates the effects of different wiring methods on the radiated emission measurement. The research result shows the standardization of wiring method has a not negligible impact on the radiated emission measurement and judgment, especially in the lower test frequency range. The research result is instructive and meaningful to the radiated emission measurement of information technology equipment.
