The Com-Power LI-325 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 LI325 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 LI 325 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.
