MC 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 postEMC compliance testing that
images realtime emissions.
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.
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.
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.
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
immunity, filtering, EMI shielding, broadband noise and Common Mode testing are
some of the applications that the EHX system addresses in mere seconds.
