Com-Power Line Impedance Stabilization Networks (LISN) are intended for electromagnetic interference (EMI) testing and certification of electronic products at an EMC test laboratory. The LISN, including this Com-Power LI-10 model, were designed and built to match the impedance characteristics given by the individual test specification. During the conducted emissions tests, the LISN LI-150 isolates the equipment under test from interference from external power source. It also stabilizes the line impedance and provides a 50Ω RF output for connecting it to the spectrum analyzer. All LISNS use air-core coils to prevent saturation and permeability variation.

The LI-150 has a separate enclosure for each network and is shipped in pairs for single phase testing. The standard configuration is two LISNs (separate assembly for each line), 4 Superior connectors, and individual calibration data.
