A LISN, implemented as a battery impedance network here, shall supply electric power to the device under test and provide a standardized impedance. It has been developed for automotive tests e.g. to fulfill the requirements of the manufacturer standard “MBN 11123”.
The BNB 8652 is constructed symmetrically with two paths, HV+ and HV-. The built in components have no specific polarity, especially not the capacitors. The paths are isolated from the housing. A foil capacitor with very low equivalent series resistance (ESR) has been used.
It is also possible to inject disturbance voltages. Inside the housing the BNB 8652 can be selected between LISN functionality and couple functionality (BNB-CN) when connecting the wires differently.
A Battery could be simulated by various internal resistors. There are three possible values: 2 x 100 mΩ, 2 x 50 mΩ, 2 x 25 mΩ (one resistance in each path).
The self-inductance between the resistance connections on the EUT side is not more than 0.5 μH.
