What is EMC (Electromagnetic Compatibility)?

EMC means that a device does not emit intended or unintended electromagnetic radiation that cause electromagnetic interference within itself or other devices in its working environment

What causes EMC Problems?

Every basic EMC problem has three components: a source that generates emissions whether intentional or unintentional, a coupling path that the source travels through and a receiver that fails to operate properly due to emissions.

How to Solve EMC Problems?

When designing or evaluating PCBs (printed circuit board), PCB Designers and Engineers employ a list of EMC design rules yet most of the time, they still fail first EMC test in an anechoic chamber.

Electromagnetic compatibility problems can generally be solved by addressing at least two of the above-mentioned components and attenuating one of them: reduce emission at its source or minimize the effectiveness of coupling path or reduce the susceptibility of the receptor to emission.

Key to the Success in EMC Compliance Tests

Time-to-market and project costs are two key factors that affect PCB Designers’ and Engineers’ success to develop an EMC compliant product. During any new product development process, they must find, characterize, and address unintended radiators or RF leakage to pass a compliance test.

The key to the success in EMC compliance test is to have immediate access to EMC data early in the design stage and see the impacts of PCB layout changes in real-time.

EMxpert: Real-time EMC and EMI Diagnostic Tool

EMxpert allows engineers to visualize the root causes of potential EMC and EMI problems. It identifies spurious signals, captures and displays near-field emissions generated by current flows on the board’s surface in seconds. It allows the design team to observe the path and mechanism leading to the creation of emissions. It also provides a detailed map of emission sources and current loops in real-time.

PCB Designers and Engineers can select and characterize specific frequencies to observe how the noise evolves spatially across the frequency range. This allows the design team to map the noise, confirm its source, and implement appropriate mitigation. Following a design modification, spectral and spatial scans will display the reductions in the level of unintentional radiations in the design in real-time.

How Does It Work?

EMxpert consists of a patented scanner and compact adaptor, and a customer-supplied spectrum analyzer and a PC running EMxpert software. The bench top scanner is composed of 1,218 H-field (magnetic) probes spaced every 7.5 mm into an electronically switched array, which provides an effective 3.75 mm resolution. The system operates from 150 kHz to 8 GHz, enabled with optional software keys.

Most of the major smart phone manufacturers, military subcontractors, antenna manufacturers, consumer electronics manufacturers and universities have added EMxpert to their test facilities.

Experts in electromagnetic compatibility and interference testing

For PCB Engineers, EMC design problems e.g. finding, characterizing and effectively addressing unintended radiators or RF leakage continues to be a persistent design challenge. This is especially true for groups designing PCBs involving high speed, high power or high density/complexity and where there is a premium on “real estate” on the board.

EMxpert allows board designers to pre-test and resolve EMC (electromagnetic compatibility) and EMI (electromagnetic interference) design problems in real-time, thus avoiding unexpected EMC compliance test results in anechoic chambers. You get insights about why designs fail, something no anechoic chamber can give you. You don’t need to wait for anechoic chamber time for design iterations or to re-design and test by trial and error. You can now rapidly diagnose even intermittent problems, which may otherwise go undetected when using handheld or automated single probes.
