E3 performs EMC pre-compliance testing to help the customers identify potential EMC issues. It does this in a cost-effective way by focusing on risk areas and quickly fixing issues that it finds during testing. It takes less time and costs less than a traditional compliance test phase. The E3 team helps customers save time and money with its process. 

By focusing on the risk areas and performing testing in a shorter time frame E3 often saves at least one product design iteration. As issues are identified the team has a full line-up of EMC troubleshooting tools to locate the source of the failure. In addition to the tools, E3 has a large number of in-house component kits to prototype solutions and retest.

Some key facts about E3's pre-compliance process include:

• Discovering product EMC issues quickly
• Finding the root cause by understanding the physics and fixing issues within the same test phase
• Performing over-testing to ensure sufficient design margin and confirm improvements
• Enabling customers to move forward confidently into their compliance test phase

EMC Pre-compliance Testing Success Stories

The E3 team had a customer request pre-compliance testing and the results showed radiated emissions failures. The team performed a design review of the schematics and PCB layout where it identified the source of the failures. The customer implemented the design recommendations and updated the product design. They built and tested the improved product and the results passed with an acceptable margin while being able to remove optional filtering components and save cost. The customer was pleased with the EMC improvements and the short timeline it was accomplished within.
