TBL0225-2 2UH LINE IMPEDANCE STABILISATION NETWORK LISN – ECSS-E-ST-20-07C
The TBL0225-2 LISN is a two-paths 50 Ω // 2 µH LISN characterized from 10Hz – 200 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 TBL0225-2 implementation aims for use in EMC measurements of 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 2 µH inductor mimics the typical inductance of the supply wire harness in spacecraft or satellites. The LISN is inserted into the power line and power return line of the EUT.
