Electromagnetic Compliance Essentials: LISN Demo, Compliance Tips, and More
Are you struggling with interference in your electronics projects, or have you ever been involved in electromagnetic compliance (EMC) testing? Check out this overview of EMC techniques, including demonstrations of noise measurement and filtering in electronic circuits.
Are you struggling with interference in your electronic projects, or have you ever been involved in EMC (electromagnetic compliance) testing? Enjoy this week’s video, which is packed with essential information on EMC, noise emissions, and practical techniques. Check it out below!
In this video, an extract from one of our recent webinars, Sebastian from Baltic Lab dives deep into this complex and often dreaded subject, offering practical insights and demonstrations. This is sure to come in handy, whether you’re working on industrial designs or hobby creations.
You’ll first learn about the importance of EMC and how to tackle noise in your designs. Sebastian starts by explaining what a LISN (Line Impedance Stabilization Network) is, complete with a clear schematic. You'll then see real-world examples using a Tekbox LISN and a Siglent oscilloscope to measure noise generated by a USB power supply. But it doesn't stop there; Sebastian also introduces the TEM cell (Transverse Electromagnetic Cell) and shows how it can be paired with a spectrum analyzer to assess radiated emissions.
The video continues with a detailed demonstration of some of the steps during pre-compliance testing for a DC to DC converter. Sebastian uses a larger LISN in combination with a Siglent spectrum analyzer to conduct the tests. Additionally, he builds a filter using a kit from Wurth Elektronik, providing a comparison of the results before and after the filter is applied.
This video is full of tips about EMC, noise emissions, and practical techniques that aren’t often shown. If you're looking to deepen your knowledge and tackle interference in your designs, watch the video below:
