Abstract

The article concerns problems of electromagnetic compatibility of contemporary IT devices. Particular attention was paid to undesirable emissions, which are by products generated unintentionally during realization of basic functions of device. In the article the methodology of measuring conducted emission on supply terminals of IT devices according to the PN-EN 55022:2006 standard in the frequency range from 0,15MHz to 30MHz has been presented as well as the methodology of measuring radiated emissivity of IT devices in accordance with the norm: PN-EN 55022:2006 in the frequency range from 30MHz to 6000MHz. Also the results of measurements conducted on particular number of central processing units have been demonstrated along with keyboards and mice produced in the years 2007 – 2009 and next their analysis has been made.

15MHz - 6000MHz频段IT设备的传导和辐射发射分析
本文讨论了当代IT设备的电磁兼容问题。特别注意的是不良排放,这是在实现设备基本功能过程中无意中产生的副产品。在文章中,根据PN-EN 55022:2006标准在0,15 mhz至30MHz的频率范围内测量IT设备供电端传导发射的方法,以及根据规范:PN-EN 55022:2006在30MHz至6000MHz的频率范围内测量IT设备的辐射发射率的方法。此外,对2007年至2009年生产的键盘和鼠标的特定数量的中央处理单元进行的测量结果也得到了证明,然后对它们进行了分析。
