TBL50100-1

Line Impedance Stabilisation Network LISN – CISPR 16

The Tekbox TBL50100-1 is a single-channel 50 Ω // 50 µH Line Impedance Stabilisation Network (LISN) designed for conducted noise measurements on AC or DC powered equipment according to CISPR 16-1-2 standards. It establishes a defined and stable impedance between the power source and the device under test (EUT), allowing accurate measurement of noise using a spectrum analyzer or EMI receiver.

Features

Key capabilities and advantages

  • Standardized 50 Ω // 50 µH LISN design for reliable conducted noise testing.
  • Supports both AC and DC supplied equipment measurements.
  • Can be used in pairs or multiples for single-phase or three-phase tests.
  • Includes BNC male to N male cable, mating connectors, and an individual calibration protocol.
  • Compatible with Tekbox LSIN-Mate to separate common-mode and differential-mode noise.
