DESCRIPTION
Line impedance stabilization networks (LISNs) are utilized during conducted emissions as well as susceptibility testing. They are specified in the EMI test requirements of various regulatory agencies, such as FCC, CISPR, FAA and DOD. Com-Power manufactures a line of LISNs which meet most specifications required by these agencies. One LISN is required for each line.
