What is a LISN
A Line Impedance Stabilization Network (LISN) is an electronic device used to measure conducted emissions in electrical and electronic equipment. It provides a stable impedance to the power line while isolating unwanted noise from external sources. The LISN connects between the power source and the device under test, allowing precise measurement of electromagnetic interference (EMI) levels.
Common LISN Uses
- Measure conducted emissions from electronic devices
- Provide stable impedance for EMC compliance testing
- Isolate noise from power sources during EMI testing
- Interface DUT’s with EMI receivers for accurate measurements
