TekBox TBL0110-2 1UH Line Impedance Stabilization Network LISN – ECSS-E-ST-20-07C Rev 1

The TBL0110-2 LISN is a two path 50 Ω // 1 µH LISN characterized from 30Hz – 500 MHz. It is based on the standard ECSS-E-ST-20-07C Rev 1. The standard provides the general schematic of the LISN and allows for some flexibility in component values. The TBL0110-2 implementation aims for use in EMC measurements of small satellites and spacecraft. The LISN does not have an output for conducted emission measurements; instead, it merely functions as a network for line impedance stabilisation. An RF current monitoring probe is used to measure conducted emissions, according to the standard.

The 1µH inductor mimics the typical inductance of the supply wire harness in small spacecraft or satellites.

The LISN is inserted into the power line and power return line of the EUT.
