About EMI Analyst

EMI Analyst was developed by NARTE-certified EMC Engineers as a design and analysis tool that can quickly, yet accurately predict EMI performance.  EMI Analyst grew out of the frustration experienced by many engineers that there simply were no cost-effective EMI analysis tools available on the market.

EMI Analyst gives electrical engineers the ability to model a circuit in a system using design information already on hand, and determine whether that circuit will meet its EMI requirements.  EMI Analyst is the first EMI analysis program that integrates all four facets of EMI - conducted emissions, radiated emissions, conducted susceptibility, and radiated susceptibility - into one program.

Before EMI Analyst was created, EMI analysis software fell into one of two categories:  overly simplified programs that attempted to implement a few mathematical formulas extracted from engineering text books or very sophisticated programs aimed at modeling complex printed circuit boards and/or systems. 

The simple programs provided only fragments of needed calculations, requiring the engineer to use various and unrelated tools to try to piece together a complete analysis.  A good analysis required an experienced, knowledgeable EMC engineer who would often use "home grown" tools to try to fill the void.  EMI analysis was very time consuming, not very accurate, and not comprehensive.

The more advanced analysis tools required extensively trained, knowledgeable engineers, with a lot of time to devote to EMI analysis.  Many of these tools required input from a CAD system, dictating that the design had to be complete before the EMI analysis could be done.

EMI Analyst overcomes the drawbacks of overly simplified and overly complex EMI analysis tools by providing a user-friendly, intuitive tool that uses information the design engineer typically has available early in the design cycle.  EMI Analyst uses sophisticated computation algorithms to provide accurate analysis results, avoiding inaccuracies inherent in many lesser tools.  At the same time EMI Analyst extracts electromagnetic characteristics from circuit and cabling design information, so the engineer doesn't have to be an EMI expert to use EMI Analyst.
