Time-efficient EMI Analysis with Test Receivers

Abstract

A system is introduced consisting of two test receivers and an intelligent monitor/control­ ler which is optimized for time-efficient ana­ lysis of all types of interference. It offers a panoramic spectrum display for manual opera­ tion, fast EMI spectrum analysis of any de­ sired frequency range and the display of the test receivers' scan results. Post scan analy­ sis is possible with zooming, markers,, display lines, NB/BB identification and CISPR-QPweighting where necessary. Moreover test receivers have the necessary overload capability for the measurement of impulsive interferenceL2D,L3D the sensitivity required to measure interfe­ rence according to national and internatio­ nal standards the required accuracy due to built-in cali­ brators (tracking and/or pulse generators) the necessary well-defined resolution band­ widths
