The main application of the unsymmetrical single path AMN (artificial mains network) NNBM 8124 is the measurement of interference voltage in vehicles, aircrafts and ships in the HF-VHF range 0.1 – 150 MHz. The NNBM 8124 can also be used for bulk current injection (BCI) testing or for transient measurements according to ISO 7637-2. Frequency range: 0.1 MHz – ~150 MHz (automotive LISN, CISPR 25 / ISO 7637).
