Langer EMV-Technik NNB 21 Line Impedance Stabilisation Network

The NNB 21 line impedance stabilisation network is designed for the **measurement of conducted interference emissions in wiring systems (automotive sector) and also for general use**. The NNB 21 can measure two circuits separately or simultaneously.

Measuring the circuits simultaneously or separately does not impact the measurement setup. This minimizes measurement errors. If there are measurements on just one signal line, the second signal path can be grounded via a side switch of NNB 21. With the attenuation and the supply of **one** source **≠ 50 Ohm**, a significantly improved adaption and more reliable measuring results can be achieved.
