TekBox TBL05100-1 LISN

Overview

The TekBox TBL05100-1 is a universal 5 µH Line Impedance Stabilisation Network (LISN) that meets the requirements of multiple EMC standards including CISPR 16-1-2, CISPR 25, MIL-STD-461G, ISO 11452-4, ISO 7637-2, and DO-160. The unit features a configurable design with internal jumper settings that allow impedance adaptation for different testing scenarios.

Factory default configuration is 50 Ω // 5 µH + 1 Ω, fulfilling CISPR 16-1-2 and CISPR 25 requirements. The LISN is inserted into the equipment under test's (EUT) supply line, where it enables monitoring of conducted noise at the EUT supply terminals via an external BNC connector using a spectrum analyzer or measurement receiver.
