a homemade lisn for precompliance conducted emission tests on dc-dc power supplies

performing precompliance measurements on power supplies requires using a line impedance stabilization network (lisn) for results that can be compared to limit values. while lisns are standard in any precompliance lab, often no lisn is available for early r&d testing. if high accuracy is not your goal and you just need a simple tool for debugging, you can build your own lisn. rohde & schwarz oscilloscopes with powerful fft analysis, are ideal for optimizing emi filters or debugging unwanted emissions during development.
