LISN
The Narda LISN series represents a comprehensive range of Line Impedance Stabilization Networks engineered for precision electromagnetic interference testing across various industries. These devices serve as a critical interface between the equipment under test (EUT) and the power supply, providing a stable, defined impedance for repeatable measurements. By isolating the EUT from external power source noise, they allow for the accurate detection of conducted emissions in accordance with global regulatory mandates. Built with decades of manufacturing expertise, these LISNs feature robust construction capable of handling significant current loads from 16 A up to 500 A. The technology incorporates high-quality chokes and bypass options, such as the 250 μH choke found in the L1-500/690V model, to ensure signal integrity across the entire frequency spectrum. Multi-standard models like the L1-150M provide switchable operations, making them easily adaptable for diverse testing environments including CISPR, ISO and specialized military requirements. The product line encompasses a vast array of models, including the L3-64 and L3-100 for heavy-duty three-phase applications.Wide Frequency Coverage
