TBL00705-2 0.7µH Line Impedance Stabilisation Network

The TBL00705-2 LISN is a two-paths 50 Ω // 0.7µH 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 TBL00705-2 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 0.7 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.
