PCB EMI-Scanners


Real-time EMC/EMI Diagnostics

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. The ERX+ has the scanner mounted on a precision positioner enabling 0.12mm resolution.

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