EHX: Real-time EMC and EMI testing system


Manufacturer's part number :


Manufacturer EMSCAN


Description :

The EHX is part of the EMxpert range from EMSCAN, and is a real-time, compact, bench-top EMC and EMI high-resolution testing tool enabling design engineers to diagnose EMC/EMI problems between 150kHz and 8GHz. The EHX provides unique pre- and post- EMC compliance testing that images real-time emissions. The EHX allows engineers to visualize the root causes of potential EMC and EMI problems.

During any new PCB development process, design engineers must find, characterise, and address unintended radiators or RF leakage to pass compliance testing. The EHX allows board designers to pre-test and resolve EMC and EMI problems early on, thus avoiding unexpected EMC compliance test results.

The 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.
