High resolution EMC and EMI testing has never been this fast! World’s fastest EMC/EMI diagnostic system has been reinvented to assist high density board designers to visualize the root causes of potential EMC and EMI problems during pre- and post EMC compliance testing.

EMScannerR+ enables the PCB and design engineers to diagnose EMC/EMI problems between 150 kHz and 8 GHz. EMScannerR+ provides 8 levels of resolution (60 microns – 7.5 mm). Level 1 resolution (7.5 mm) allows the engineers to visualize the hot spots, current loops or intermittent problems in real-time. After locating the unintended radiators, engineers can zoom into the problem by selecting the resolution level based on the density of the board design.

EMScannerR+ provides unique pre- and post-EMC compliance testing that images emissions. During any new PCB development process, design engineers must find, characterize, and address unintended radiators or RF leakage to pass compliance testing. EMScannerR+ allows board designers to pre-test and resolve EMC and EMI problems early on, thus avoiding unexpected EMC compliance test results.

EMScannerR+ quickly delivers repeatable and reliable results that pinpoint the cause of a design failure. As a result, the user can personally test the design without having to rely on another department, test engineer, or time-consuming off-site testing. After diagnosing even an intermittent problem, the engineer can implement a design change and retest. The results provide concrete verification of the effectiveness (or not) of the design change.
