A LISN, implemented as a battery impedance network here, shall supply electric power to the device under test (DuT) 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 8655 is constructed symmetrically with two paths, HV+ and HV–, with variable power resistors in each path. A battery can be simulated by various internal resistors. Three possible values are available for Rint: 2 x 100 mΩ, 2 x 50 mΩ and 2 x 25 mΩ (one resistor in each path). The built in components have no specific polarity. Both paths are isolated from ground.
