Abstract： Pulse-modulated noise （PWN） serves as auseful class of artificial test waveforms for electromagnetic interface （EMI）and electromagneticcapability（EMC）testing，capable of characterizing a widerange of interference vulnerabilities on communication links.In this paper，we propose methods based on multi-carrier PWN signal generation and multi-carrier in-band spectrum control. We demonstrate precise control of PWN when square wave frequenciesrangingfrom1MHzto 20MHz ，dutycycle ranging from 0% to 100% ，andGaussianwhitenoisewith bandwidths spanning 50 MHz to 400MHz .The proposed method can be utilized for effective pulse-modulated noise for testing modern digital wireless system.
