Due to the very strict specifications regarding impedance tolerance in VW 80300:2021-02 (±10%) and the physically achievable measurement uncertainty for resistance measurements in the milliohm range, a few values approach, touch, or even slightly exceed the limit line. This affects only a few measurements and is unavoidable, which is why compliance with this standard is indicated in parentheses.
The BNB 8652 B is constructed symmetrically with two paths: HV+ and HV-. The built-in components have no specific polarity; in particular, the capacitors are non-polarized. The paths are isolated from the housing. A foil capacitor with very low equivalent series resistance (ESR) is used.
It is also possible to inject disturbance voltages. Inside the housing, the BNB 8652 B can be reconfigured from LISN functionality to coupling functionality (BNB-CN) by changing the wiring connections.
A battery can be simulated by various internal resistors. There are five selectable values: 2 × 100 mΩ, 2 × 60 mΩ, 2 × 50 mΩ, 2 × 25 mΩ, and 2 × 10 mΩ (one resistor in each path).
The self-inductance between the resistance connections on the EUT side is no more than 0.5 μH.
