NEW! Check out our video "How to measure effectiveness of a filter early in the design cycle before the anechoic chamber test". Click here for the video.
NEW! High resolution EMC and EMI testing has never been this fast! (min. resolution ≈ 120 microns). ERX+ is the world's fastest high resolution EMC scanner.
EMC performance can be improved by modifying the PCB layout, components, re-routing PCB tracks and etc. Identifying the potential areas for malfunction and correcting them at the design stage will significantly reduce the cost and time of modification at the post-testing stage or later.
PCB designers use filtering component to avoid unpleasant problems late in a product design cycle. EMI filtering is another way to minimize susceptibility to radiated spurious signals in noise sensitive circuits.
EMxpert shows the effectiveness of filtering in real-time, by immediately mapping near-field emissions from current flow on the surface of your board. It also allows you to compare different versions by using Spatial Comparison in seconds.
