NSLK 8117, 9 kHz - 30 MHz, 250 VAC / 10A, 50 µH, 2 Path LISN

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 8117 is equipped with a 250 μH choke as well as 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.

The supply voltage has to be applied at the back panel of the LISN by using the Schuko connector. Important! The operator has to make sure that the maximum current is limited to 10 A at the supply side. There is no fuse built into this LISN to protect the device under test! The device under test has to be connected to the Schuko socket at the front panel. The maximum current that can be drawn is 10 A for each path. The maximum voltage that can be applied is 250 VAC. The input for the power supply is located at the back panel and provides a hard-wired connection cable with a Schuko plug. The coaxial RF output has to be connected to the EMI measurement receiver using a BNC coaxial cable. The other connector should be terminated with a 50 Ohm termination.

The NSLK 8117 is equipped with a high pass filter but not with a pulse limiter. The EMI receiver should therefore be protected against overload. The VTSD 9561 F is an external pulse limiter that is suitable for this purpose. If the amplitude of the disturbance voltage exceeds values which could be dangerous for the EMI receiver input the pulse limiter will cut these pulses. This causes additional spectral lines in the frequency domain (“phantom spectral lines”). The excess-pulse-energy illuminates an electric bulb. If the bulb glows or lights up the measurement is not valid because of the phantom spectral lines. In such a case more attenuation must be used at the measuring port of the LISN. An external attenuator must be dimensioned sufficiently especially under the presence of strong harmonics of the mains frequency
