  • Patent number: 6529020
    Abstract: A system for measuring electromagnetic emissions from electronic devices includes an semi-anechoic chamber, a computer, an EMI receiver, and a multi-device controller. The chamber houses devices being tested and test equipment for automated emissions scanning. The computer receives emissions data from test equipment housed within and outside the chamber and operates a multi-device controller which controls the test equipment. The method includes wide-band measurements of emissions, narrow-band measurements of emissions chosen from the wide-band measurement, determining a maximum quasi-peak value for optimal cable and wiring position, and communicating results to a word-processing program to report measured values against testing limits.
