Line impedance stabilization network (LISNs) are typically used for conducted emissions testing to CISPR or FCC standards designed to limit the noise created along conducted paths, typically power mains cables. The LISNs provide a way to monitor the noise that a particular product or electrical is coupling or creating. We offer a variety of different equipment capabile of up to 50amps allowing for higher current EUT to be evaluated. Typically this testing is some of the most common failures during the EMC product evaluation process often leading to precompliance and retesting should failures arrise. Transient specialists offers a wide range of both LISNs and current monitoring probes designed for conducted emissions testing where other equipment is not suiteable.
