World’s fastest bench-top system to diagnose and debug EMC/EMI design problems: EMxpert

EMxpert provides spatial and spectral scans that allow design teams to address EMC design problems at their lab-bench in real-time.

Spectral scan measures and displays the maximum amplitude vs. frequency of the magnetic field strength over the scanned area. To characterize emissions, EMxpert quickly scans the board across a broad frequency range (150 kHz – 8 GHz). You can then 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. A spectral scan result is shown below. You can mouse over the spectral graph and analyze the problem frequency and amplitude.

Spatial scan measures the magnetic field of radiated electromagnetic emissions from the DUT at a single frequency as a function of position. EMxpert maps near-field emissions generated by current flow on the surface of the board. Measurements occur in real-time and this allows the design team to compare different design versions in seconds using the Spatial Comparison capabilities of the instrument. A spatial scan result is shown below. You can import the Gerber file of the PCB or simply the picture of the PCB. You can exactly find the location of the hot spot or current loop or intermittent event when you mouse over the graph.

EMxpert allows the design teams to diagnose and quickly address any unexpected emission problems with the EMC design. It will cut one to two design cycles out of your product development process. It also reduces their EMI testing time by up to two orders of magnitude.

Why EMxpert Is Right For You

You can execute real-time analysis of your design, test multiple design iterations and optimize complex designs on your lab-bench in seconds at each stage of the design process.

Are you under time-to-market pressure because of the countless number of lengthy measurements in inaccessible anechoic chambers?

Tired of losing valuable project time waiting in line to test your designs in expensive anechoic chambers?

Do you want to test your design and performance quickly to accelerate project completion and delivery?

Are you under budget pressures?

Why did your product fail the compliance test in an anechoic chamber? Why didn’t you see this coming?

With EMxpert, in seconds and a fraction of an anechoic chamber cost you can easily:

  • Analyze your high speed, high power and/or high density/complexity PCB designs.
  • Visualize the root causes of potential EMC and EMI problems.
  • Find, characterize, and address unintended radiators or RF leakage.
  • Pinpoint the cause of a design failure even when the problem is intermittent.
  • Prototype, test, and optimize new designs, forms and components.
  • Test & optimize multiple PCB (printed circuit board) design iterations on your lab-bench.
  • Resolve EMC and EMI problems early in the design cycle

  •   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).

    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.”

“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.”
