Compliant with standards CISPR 16-1-2, CISPR 25, EN 55025, MIL-STD-461F.
**Product Overview** The TBL0550-1 5µH LISN is a device necessary for setting up conducted noise measurements of electronic equipment powered by DC sources. It is designed to comply with CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, and ISO11452-4, and is intended for measurements in the frequency range of 150kHz to 110MHz, with limited use of DO-160 / ED-14G and ISO7637-2. The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise present at the power terminals of the DUT can be measured via a BNC connector using a spectrum analyzer or measurement receiver. The source (power) terminal and the DUT terminal are decoupled by a 5µH inductor. By combining two TBL0550-1 units with the Tekbox LISN Mate, common mode noise and differential mode noise can be measured separately. The unit is equipped with a BNC male-N-male RG232 cable, coupling connectors, and a ground bracket for connection to a ground plane.
