N2 - In general, the EMI problems of Printed circuit board (PCB) are caused by a variety of factors, such as ringing signal, clock signal and differential pairs of non-equal length. These problems are not easy to find and distinguish in the RE102 test, which will make difficult to the Subsequent rectification. In this paper, by analyzing the spectrum characteristics of the ringing signal in the DC-DC converter, we propose methods for identifying and suppressing the ringing signal interference. These methods can quickly determine the broadband EMI caused by the DC-DC converter from the RE102 test result of the DUT, and effectively guide the rectification program to suppress the EMI. The actual test result is given in the paper, which proves the effectiveness of the method.
