FCC-LISN-50-50-4-02 Overview
The FCC-LISN-50-50-4-02 is a Line Impedance Stabilization Network for the measurement of line-conducted interference within the range of 9 kHz to 30MHz, according to the CISPR 16-1-2 standard. The device is designed for testing 3-phase and single phase, AC powered equipment with supply voltages up to maximum 450V/260V and 32A. Conducted noise can be measured on each phase and on the neutral conductor. The FCC-LISN-50-50-4-02 has separate RF outputs for each phase and neutral and consequently can be coupled with the LISN-CISPR to split the emissions in its common mode and differential mode components. The LISN-CISPR16- 32A has no integrated high pass filter at the RF outputs, but comes with an external 9 kHz coaxial high pass instead. The single-phase DUT socket is available in country-specific variants.
