The impedance characteristics are basically realized by connecting an inductor in parallel with the input impedance of the measurement receiver: 5 µH || 50 Ω.
The LISN has been designed to be installed in pairs into a shielded housing HVSE 8600. Each NNHV 8123 200R can be used to measure one single path. To be able to measure HV+ and HV- two units are required. The device under test has to be connected to the terminal at the front panel. The supply voltage has to be connected at the back panel. The shielding of the cable is connected to the HVSE 8600 feedthrough.
The device under test may drain a continuous current of 200 A and for a short period of time it may even drain more than 280 A.
With its high voltage and current specification this automotive LISN fits well for electric vehicle (EV), hybrid drive and on-board battery electronics testing.
