TBL05100-1-B

Line Impedance Stabilisation Network

The TBL05100-1-B is a universal 5µH LISN that meets the requirements of several standards. The TBL05100 is factory jumpered to 50Ω // 5µH + 1Ω, fulfilling the CISPR 16-1-2 and CISPR 25 impedance, phase an isolation specification. By setting internal jumper, it can be converted into 50Ω // 5µH variants that support standards such as CISPR 25, MIL-STD-461G, ISO11452-4 and ISO 7637-2. By adding an external 10F capacitor, the impedance will fulfil DO-160 specifications. The LISN is inserted into the EUT’s (Equipment Under Test) supply line. Conducted noise at the EUT’s supply terminals can be monitored at the BNC connector with a spectrum analyzer or a measurement 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 for the measurement of common mode and differential mode noise separately. The unit comes equipped with a BNC-male to N-male RG232 cable, mating connectors and ground brackets to attach it to a ground plane.
