The TBL0550-1 5µH LISN is a device required for setting up conducted noise measurements of DC powered electronic devices. It is intended for measurements in the frequency range 150kHz to 110 MHz according to CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, ISO11452-4 and with limitations DO-160/ED-14G and ISO 7637-2 .
The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted interference that is present on the supply connections of the test object can be measured on the BNC connector with a spectrum analyzer or a measurement receiver. The source (supply) terminal and the DUT terminal are decoupled by an inductance of 5µH.
Two TBL0550-1 in combination with the Tekbox LISN Mate enable the separate measurement of common mode and differential mode noise.
The device is equipped with a BNC male to N male RG232 cable, mating connectors and grounding clips for attachment to a ground plane.
