TBL05100-1-C 5uH 100A Line Impedance Stabilisation Network LISN
The TBL05100-1C is a universal 5µH LISN that meets the requirements of several standards. The TBL05100-1C 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 10uF 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 TBL05100-1C 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 N-male to N-male RG232 cable, mating connectors and ground brackets to attach it to a ground plane.
Topology: single path, configurable, 50Ω // 5µH + 1Ω, 50Ω // 5µH; the internal capacitor can be disconnected for ISO 7637-2 and DO-160 set ups; an external 10µF capacitor is required for DO-160; the LISN is factory setup to 50Ω // 5µH + 1Ω, other configurations require setting of an internal high current jumper.
