LI-400 Com-Power LISN

The LI-400 is a new LISN from Com-Power. A line impedance stabilization network (LISN) device is something engineers use to test radiofrequency (RF) emission and susceptibility. During an electronic equipment test, engineers place the LISN device between an alternating current or direct current power source and the equipment under test.

The Com-Power LI-400 Line Impedance Stabilization Network (LISNs) is utilized during conducted emissions as well as susceptibility testing. It is specified in the EMI test requirements of various regulatory agencies, such as FCC, CISPR, FAA and DOD.

The Com-Power LI-400 provides input power impedance to the EUT that is constant and independent of the line impedance. As a result, the test engineer will be able to gather consistent test data.

The Com-Power LI-400 has an aluminum enclosure that minimizes radio frequency interference which can compromise test results and use air-core coils to prevent saturation and permeability variation.
