Schwarzbeck NSLK 8130 Line Impedance Stabilisation Network

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

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

The supply voltage has to be applied at the back panel of the LISN by using the wing terminals.The device under test has to be connected to the wing terminals at the front panel.

The coaxial RF output has to be connected to the EMI measurement receiver using a BNC coaxial cable. You can choose the path that needs to be measured with the path selection switch. The paths that are actually not measured will be terminated with 50 ? automatically.
