Title: Methods and systems for automated emissions measuring

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