Finding, characterising and effectively addressing unintended radiators (EMI/EMC) or RF leakage continues to be a persistent design challenge for groups doing designs involving high speed, high power or high density/complexity with a premium on ‘real estate’.
EMXpert from EMSCAN is a magnetic near-field scanning system that helps designers be highly productive in understanding and diagnosing these problems, quickly and early in the development cycle. This assists the developer to accelerate the time to market because frequencies causing problems can be identified and eliminated before sending boards for qualification.
The system primarily provides designers with a very rapid and highly repeatable measurement approach to identify problem frequencies, problem sources (and their physical location) contributing to EMI and RF leakage issues in PCB/PCP designs or within integrated configured systems. EMXpert supports a variety of high-speed scanning options, and interfaces with a broad range of the most prevalent spectrum analysers from the most popular manufacturers.
The system manages the scanning options and the processing chosen, along with the subsequent analysis of the collected data. It has a spectral scan feature to identify problem frequencies on a circuit board by measuring and plotting the peak amplitudes for a chosen range of frequencies. Once a problem frequency is identified, a spatial scan is used to map the location and amplitude of that frequency on the circuit board. The user can zoom in/out the graphic to analyse the problem frequencies.
