A Guide to Conducting In-House Pre-Compliance EMC Testing!Randy Mitchell
A Guide to Conducting In-House Pre-Compliance EMC Testing! Electromagnetic Compatibility (EMC) is a critical consideration for electronic product manufacturers. Compliance with EMC ensures that your devices don’t interfere with other electronic equipment and function reliably. During development, Pre-Compliance EMC Testing is a valuable, cost-effective way to identify and rectify potential issues. Here’s a guide to help you get going:
- Understand the EMC Requirements- Learn the EMC regulations that apply to your product market.
- Set up a Testing Area- Dedicate a controlled interference free space for testing, an RF Shielded Enclosure of the proper size is ideal.
- Equip Yourself-invest in the necessary testing equipment, including spectrum analyzers, oscilloscopes, and others.
- Test Standards-Identify the relevant EMC standards for your product such as EN 55032 or FCC Part 15. Understand the test methods outlined in the standards.
- Prepare Your Samples-Ensure that your product samples are in a functional state and compliant with EMC guidelines.
- Develop a Test Plan- Create a detailed test plan and procedure that outlines the test to be conducted, measurement points, and pass/fail criteria.
- Conduct Emissions Testing- Evaluate conducted emissions to assess interference generated through signal and power cables.
- Radiated Emissions Testing- Measure radiated emissions using antennas and spectrum analyzers, comparing results to standards.
- Immunity Testing-Test your product’s resistance to EMI.
- Data Analysis-Analyze test data, honing your product so that it is compliant.
- Documentation-Maintain thorough records of all testing data, procedures and equipment operation.
- Training-Ensure your team is familiar with the equipment ready to perform EMC testing procedures.
- Repeat Testing-Repeat the testing until your product meets EMC Requirements.
In-house Pre-Compliance EMC testing requires substantial investment in equipment, training and resources. Once you’re confident your device is ready, Proceed with Final EMC certification Testing.
