LISNs

LISNs, or line impedance stabilization networks, are instruments used in conducted and radiated EMC emissions and susceptibility testing. Primarily, LISNs provide an accurate impedance and radio frequency to the equipment/device under test (EUT/DUT). The goal of this testing is to get repeatable measurements of the EUT noise that is present at the LISN measurement port. LISNs also play a role in preventing high-frequency noise emitted by a power source from coupling in the system, isolating unwanted radio frequency (RF) signals from the power source. There are a variety of LISNs for analyzing DC, single-phase and three-phase AC power connections. Attributes such as voltage rating, current rating, number of power conductors, and insertion loss are all helpful variables to keep in mind when selecting a LISN to most effectively complete your testing.

Advanced Test Equipment Rentals carries a wide selection of LISNs for conducted emissions testing for IEC, MIL-STD, CISPR 16, and other EMC test standards. ATEC offers equipment from top EMC equipment providers like Chase, Com-Power, Solar, EMCO, and more.
