Cranage LISN Model P2129 One Line V-Network (CISPR25)


General

This LISN complies with CISPR25 specifications for vehicle components and modules. It is used in conjunction with a spectrum analyser or receiver for measuring high frequency noise conducted on DC power lines and is located between the incoming power supply and the Equipment Under Test (EUT).

Technical Specification

 Model P2129 LISN is a three terminal device, one terminal earthed, to be series connected between the power source and the DC power input of the EUT. It is a robust, high stability unit which meets the impedance/frequency characteristics specified in CISPR25. A shielded input capacitor (4mF) is incorporated for improved isolation performance. The measurement socket is intended to be externally terminted at 50W by the measuring equipment. The case of the LISN is bonded to the ground plane via four M6 screws. An M8 earth stud is also provided for additional earth bonding.
