A LISN, here implemented as a battery impedance network, 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 standards ISO 21498-2:2021-03 and MBN 11123:2021-08.
The BNB 8654 C is constructed symmetrically with two paths, “HV+” and “HV-“, with selectable power resistors in each path.
A battery can be simulated by various internal resistors. Six possible values are available for Rint: 2 x 100 mΩ, 2 x 60 mΩ, 2 x 50 mΩ, 2 x 25 mΩ, 2 x 10 mΩ and 0 Ω (one resistor in each path).
