Isolate the power and data lines to your DUT (device under test) to eliminate outside and unknown electrical noises, providing a stable impedance during your testing. Line impedance stabilization networks (LISN's) are used for electromagnetic compliance testing as well as engineering labs for better performance and more accurate measurements.
