TekBox TBL0550-1 5UH 50A LISN (line impedance stabilization network) - CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, ISO11452-4

The TBL0550-1 5µH LISN is an equipment used to configure noise measurements conducted by DC-powered electronic equipment. It is designed to be used for measurements in the frequency range from 150 kHz to 110 MHz in accordance with CISPR 16-1-1-2, CISPR-25, EN55025, MIL-STD-461F, ISO11452-4 standards and with DO-160 / ED- 14G and ISO 7637-2 limitations.
The LISN is inserted into the power supply line of the DUT (Device Under Test).
The conducted disturbance present at the power terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or measurement receiver.
The source terminal (power supply) and the DUT terminal are decoupled by a 5µH inductor.
Two TBL0550-1 in combination with Tekbox LISN Mate enable separate measurement of common mode and differential mode noise.
The unit is equipped with an RG232 BNC-male to N-male cable, mating connectors, and grounding brackets that allow attachment to a ground plane.
