EMI debugging and analysis

EMI debugging in the design phase will help keep product development on schedule

Detecting, analyzing, and correcting causes of electromagnetic interference (EMI) early in the development process is the surest way to successfully pass an EMI compliance test and the best way to avoid redesigns, delays, and added costs late in a project. EMI debugging for unwanted emissions can start as soon as a circuit is live.

Rohde & Schwarz supply multipurpose equipment including oscilloscopes with leading FFT functions, advanced trigger possibilities and very low input noise, and spectrum analyzers featuring high sensitivity and accuracy with EMI options to confidently measure both conducted and radiated emissions. Sensitive EMC near-field probes as input sources complement the product portfolio.

Solving EMI problems early in the design cycle is more cost-effective than solving them later. This is an iterative process of employing best practices and checking. Of course, it is a trade-off – and needs to be balanced against functionality and scheduling. But solving problems and verifying early helps reduce costs. This poster helps you to design with EMI in mind.
