W H I T E P A P E R EMC Pre-Compliance Fundamentals Once you’ve designed your electronic product, it’s time to release it to market, right? Well, not exactly. As with any product development, you need to first test the device you’re designing to validate that it behaves as expected. One Conducting pre-compliance such important test that all electronic devices must eventually pass are EMI tests are important to do (electromagnetic interference) compliance tests. Passing EMI tests demonstrate so that you not only ensure that your device’s electromagnetic emissions are at an acceptable level, as defined your device is certified for compliance at a test by the respective regulatory body’s standard the device is being tested against. facility, but also to maintain an on-schedule product EMI, or electromagnetic interference, falls under the umbrella term ‘EMC’ which development cycle. stands for electromagnetic compatibility. When performing pre-compliance tests, you are concerned about testing for EMI which is the actual phenomena – or emissions – coming from your device. However, acquiring certification for EMI compliance testing is rather expensive – and in the off chance that you don’t pass – you not only have to rework your des
