NNLK 8129-2 HV, 150 kHz - 30 MHz, 1000 VAC / 200A, 50 µH, 2 Path LISN

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.

Artificial mains networks from the NNLK line do not have the pre-filter choke contrary to the NSLK line (exception: NNLK 8121). This is due to the high current rating and complies with the CISPR 16-1-2 standard for LISN’s for band B. They basically work in band A also but are specified starting from 150 kHz.

Options:

Opt. RC

Option RC for LISN: Remote Control with built-in power supply. LISN can be controlled by R&S or Schwarzbeck code, including remote control cable for your receiver type (Please specify your receiver type!). LISN can be selected from the R&S receiver menu or in the EMC32 software like an R&S LISN. No programming of the user interfaces necessary. Functions: path selection and PE grounded or via choke.

   

Opt. TC

The temperature monitor module which is optionally available for the NNLK LISN warns the user visually and acoustically when the temperature gets too high. It controls the fans of the LISN temperature-dependent, too, and thus prevents overheating. If a critical temperature is reached the temperature control module indicates this optically and acoustically.

 

 

 

The NNLK 8129-2 HV 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
