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 8601. Each NNHV 8123 800R can be used to measure one single path. To be able to measure HV+ and HV-, 2 units are required. The equipment 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 8601 feedthrough.
With its high voltage and current specification this automotive LISN fits well for electric vehicle (EV), hybrid drive and on-board battery electronics testing.
