This paper describes the results of calculating and measuring deviations of conducted disturbance voltages caused by differences in the arrangement of an artificial mains network (AMN) used to measure the voltage, for example, the height of the (AMN) from a horizontal reference ground plane and the connection between the AMN and the ground plane. The results indicated that the conducted disturbance...
In recent years, personal computers have been constructed by combining modules such as a hard disc drive and memory boards. Although a simple method for measuring disturbances from such modules in the frequency range below 1 GHz has been proposed, device technology progress needs an evaluation method above 1 GHz. This paper describes a method using a magnetic probe for measuring disturbances in the...
VCCI had started Kit Module Program in 2005 in order to control EMI of the modules. In this program, the electric current on the power line (PL) of the power distribution network (PDN) on the printed circuit board (PCB) is measured by the magnetic probe (MP) method which has been standardized by IEC for the EMI testing of LSI. In this paper, the test result of several kinds of module is presented...
