Schwarzbeck NSLK 8163 Line Impedance Stabilisation Network

The purpose of a LISN is to provide the device under test with energy, to carry the interference voltage to the EMI measurement receiver and to load the RF emitted by the device under test with standardized impedance.

The NSLK 8163 is equipped with a 250 µH choke as well as with a 50 µH choke which is connected in series for each path. The 250 µH choke provides an excellent decoupling between the power supply and the device under test starting at 9 kHz.

Due to high capacities very high leakage currents can occur (above 1 A). Thus it is not possible to use a residual current operated circuit breaker. It is recommended to use an isolating transformer.
