Schwarzbeck NNLK 8129

Description
A V-LISN from the series of the NNLK line is required to measure conducted interference voltages according to VDE-, CISPR- and related standards. It provides the device under test with a mains connection that has a standardized impedance of 50 Ω || 50 µH and reduces interference voltages coming from mains. The interference voltage of the device under test is decoupled via a 7 kHz high pass filter to the EMI measurement receiver.
A path selector switch allows measuring both paths, one after another. The paths that are not being measured are internally terminated with 50 Ω
For measurements conforming to standards the references in the standard CISPR 16-2-1 have to be followed. Amongst others it is described that the AMN has to be grounded with a short and wide ground strap to the wall of the shielded chamber (or provisionally to a sheet metal board at the wall).
