Real-time EMC and EMI diagnostic tool: Test ultra-high speed (>2GHz) PCBs in real-time on your lab-bench

EMC and signal integrity are major concerns in the design of ultra-high speed (>2GHz) PCBs. EHX enables the design engineers to diagnose EMC/EMI problems between 150kHz and 8GHz. The EHX provides unique pre- and post-EMC compliance testing that images realtime emissions. EHX allows engineers to visualize the root causes of potential EMC and EMI problems. During any new PCB development process, design engineers must find, characterize, and address unintended radiators or RF leakage to pass compliance testing. EHX allows board designers to pre-test and resolve EMC and EMI problems early on, thus avoiding unexpected EMC compliance test results. EHX delivers repeatable and reliable results that pinpoint in less than a second 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

 EHX consists of a patented scanner and compact adaptor, and of a customer-supplied spectrum analyzer and PC running EHX software. EHX diagnostic capabilities allow design teams to reduce testing time by more than two orders of magnitude. Users have also documented fifty percent reductions in design cycle times. This allows the design team to immediately analyze and compare design iterations. Ideal PCB projects for EHX are boards designed for high speed, high power, and/or high density/complexity. Any PCB that places a premium on board real-estate also qualifies as an excellent candidate. The compact, flat scanner provides PCB design teams with an easy-to-use, cost-effective, and proven tabletop solution. Emission, immunity, filtering, EMI shielding, broadband noise and Common Mode testing are some of the applications that the EHX system addresses in mere seconds.
