Analysis of wiring in the radiated disturbance measurement of electronic equipment

The article illustrates that the wiring method has non-negligible impact on the radiated disturbance measurement of electronic equipment. The influence of wiring pattern has been analyzed during the measurement of radiated emission based upon the different laying manner of video wire, audio wire, keyboard wire, mouse wire and universal serial bus wire. Furthermore, the effect has been evaluated under such different cable arrangement in the radiated emission test. The research result shows the standardization arrangement of wiring has an important influence on the radiated disturbance measurement and result judgment, especially in the lower frequency range. The research result is meaningful and persuasive to the radiated disturbance measurement of electronic equipment in a correct and standardized way.
