TBL5063-3
Line Impedance Stabilisation Network LISN
The Tekbox TBL5063-3 is a professional-grade Line Impedance Stabilisation Network (LISN) designed for conducted emission measurements on three-phase AC-powered equipment. It provides a defined and stable impedance between the power source and the equipment under test (EUT) so that noise can be measured accurately using a spectrum analyzer or EMI receiver according to the CISPR 16-1-2 standard.
