BNB 8656 has been developed for automotive tests e.g. to fulfill the requirements of the manufacturer standard ISO 21498-2:2021-03, MBN 11123:2021-08, BMW 95024 2 2:2011-02, PSA B21 7112:2021-05, (VW 80300:2021 02). A LISN, implemented as a battery impedance network here, shall supply electric power to the equipment under test (EuT) and provide a standardized impedance.
The BNB 8656 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. Five possible values are available for Rint: 2 x 100 mΩ, 2 x 60 mΩ, 2 x 50 mΩ, 2 x 25 mΩ and 2 x 10 mΩ (one resistor in each path).
