 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 interface necessary. Functions: path selection and PE grounded or via choke.

 Opt. Hochstrom:

Option: cont. high current, additional terminals to bypass the 250 µH prefilter-chokes, provides less voltage drop and less heating.

 Opt. 400/700 V:

 Option: 400/700 V Voltage to ground / Voltage between lines


 Opt. Lüfter:

 Option: Cooling Fans


Opt. TC:

The temperature monitor modul which is optional available for the NNLK LISN warns the user optical and acoustical 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 modul indicates this optically and acoustically.
