    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.

  •   How does the EHX work?

    how-does-it-workThe EMxpert EHX consists of a patented scanner, a compact adapter, a customer-supplied spectrum analyzer and a PC running EMxpert software (EMxpert setup diagram). The EMxpert EHX measures the magnetic field (H-Field) in two orthogonal directions using H-field probes.

    The patented scanner is a passive device that couples the very-near-field emissions from the device under test. The measurements of these coupled fields are done with the spectrum analyzer and the adaptor synchronizes the spectrum analyzer and the patented scanner.

    The EMxpert software knows the insertion loss of each individual probe across the frequency range so it can apply compensation for the internal losses of the scanner.

    The software will also apply the antenna factor compensation that will result in accurate H-field data being displayed. Interpolation between probes is done by the software so that features smaller than the probe spacing can be resolved.

    The patented scanner consists of 1,218 H-field (magnetic) probes that operate between 150 kHz and 8 GHz. Probes are wide band but not very sensitive across this band thus they are very good at rejecting background noise.

    Each row and column on the patented scanner corresponds to a unique probe that is spaced every 7.5 mm into an electronically switched array, which provides an effective 3.75 mm resolution. Electronic switches enable the probes to sweep the entire board under one second.

  •   How does the EHX+ work?

    how-does-it-workThe EMxpert EHX+ consists of a patented scanner, a built-in adapter, a built-in spectrum analyzer and a customer-supplied PC running EMxpert software (EMxpert setup diagram). The EMxpert EHX+ measures the magnetic field (H-Field) in two orthogonal directions using H-field probes.

    Each row and column on the patented scanner corresponds to a unique probe that is spaced every 7.5 mm into an electronically switched array, which provides an effective 3.75 mm resolution. Electronic switches enable the probes to sweep the entire board under one second when Level 1 is selected.

    The scanner is placed right under the Gorilla Glass. X/Y step motors move the scanner (1218 probes) for higher resolution scans under the Gorilla Glass. After placing the DUT on the Gorilla Glass, user can select from seven different levels of resolution (0.12 mm – 7.5 mm).

    The image on right is a representation of a 2 x 2 scan area on the scanner. At level 1, spatial scan is executed in real-time i.e. scanner doesn’t move. The data is collected by each probe that is placed in the center of each grid.

    At level 2, each grid is divided into four subgrids. Scanner first moves the orange dots and collects data from four subgrids. Scanner then moves to black dots and collects data from four subgrids. Scanner then moves to green dots and collects data from four subgrids and finally, scanner moves to purple dots and completes the scan.

    At each level, one grid is divided into four subgrids which means four measurement points. Level 7 is the highest resolution (120 microns) and the maximum number of measurement points in one grid can be 4,096.

Companies Who Trust EMxpert Products
What Our Customers Are Saying
“I’m an electronics technician with 30 plus years in the automotive electronics field. We could not afford to spend a lot of time and money at the end of the development cycle trying to fix EMC failures, especially at the expensive certified EMC labs that we used for final compliance testing. Our in house EMC lab was used for pre-compliance testing, we were not certified. For susceptibility testing we did: strip line, TEM cell, tri-plate and bulk current injection. This is where EMxpert comes in. When you’re doing susceptibility testing and there is an anomaly, it may not be apparent as to what part of the circuit is malfunctioning. For EMC, it is all about the up-front work that is done. Board layout and pre-compliance testing are very important. The farther into the design cycle you are, the more it will cost you to resolve it. If I had to describe EMxpert in one word it would be “up-front”. It’s like your headlights in the dark.”

Lectron
“I was very impressed with the capability of the EMxpert solution. We had spent several weeks investigating EMC issues related to our end customers product. We had information relating to the spectral component and amplitudes that were causing an issue, but needed to identify the location of the emission site. The EMxpert tool allowed us to perform spatial analysis and locate the site in a single day. The tool is effective and can save weeks of time and effort!”

“Where have you guys been for the last 5 years while we have struggled?” was the concluding comment from Robert… “We need one of these” was Robert’s conclusion.”
