Short description
The NNB 21 line impedance stabilisation network is designed for measuring conducted
disturbance emission of a device under test according to the standard CISPR 25/ISO 7637.
It measures the RF interference, which couples into the vehicle electrical system. Measurements during the development in a frequency range from 100 kHz to 1GHz can be carried out.
