Good Board vs Bad Board Analysis
Trở thành kỹ sư thiết kế chuyên nghiệp với chuỗi video hướng dẫn kiểm định EMI/EMC trên thiết bị EMScanner!

In this video you will learn about good versus bad board layout by using the filter circuit. The short layout circuit has less return path current compared to the big layout circuit which has very high current in the return path. This is seen practically in analysis of the board where the maximum amplitude of distortion occurs at the harmonics of the clock frequency 24MHz.

First very near field Spatial Analysis of continuous scan is done using the software to find the difference in amplitude of distortion for the good versus bad layout. 

Second very near field Spectral Analysis for the band of frequencies from 10MHz to 200MHz is done continuously to determine the amplitudes of distortion for good versus bad board.

Next we generate the project report immediately for all the scans which is useful for verification purposes
