LISN-CISPR25 Single Path Automotive Line Impedance Stabilization Network

LISN-CISPR25 Single Path Automotive Line Impedance Stabilization Network is a low-pass filter typically placed between a DC power source and the EUT (Equipment Under Test) to create a known impedance as per complying standard for the measurement of conducted emission.

It also isolates the unwanted RF signals from the power source with pre-filter included. It provides a Radio frequency (RF) noise measurement port. In addition LISN is used to predict conducted emission for diagnostic, pre-compliance and compliance testing. These single line LISNs are used in automotive industries and test labs for measurement of interface voltages in vehicles, EVs, Ships, Aircrafts, etc.

The characteristic impedance is designed as per CISPR 25 of these LISNs is (5 ) || μH + 1Ω 50 Ω These LISN also can be used in immunity test by bulk current injection and transients as per ISO7637-2 standards. A Transient limiter is highly recommended to use with LISN at the front end of EMI Rx or Spectrum Analyzer to protect measuring instrument from transients.
