TekBox TBL05100-1B

The TBL05100-1-B is a universal 5µH LISN that meets the requirements of multiple standards. The TBL05100 is jumpered at the factory to 50Ω // 5µH

• 1Ω and meets the impedance, phase and isolation specifications of CISPR 16-1-2 and CISPR 25. By setting an internal jumper, it can be converted to 50Ω // 5µH variants supporting standards such as CISPR 25, MIL-STD-461G, ISO11452-4 and ISO 7637-2. By adding an external 10F capacitor, the impedance meets DO-160 specifications.

The LISN is inserted into the EUT's supply line. Conducted noise at the EUT's supply terminals can be monitored at the BNC connector with a spectrum analyser or test receiver. A 5µH inductor decouples the source (supply) terminal from the EUT terminal.

The use of two TBL05100-1-B in conjunction with the Tekbox LISN Mate allows common mode and differential mode noise to be measured separately. The unit is supplied with a BNC male to N male RG232 cable, mating connectors and grounding brackets for mounting to a ground plane.
