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.
The impedance characteristic is realized according to CISPR 16 / 25 and MIL STD 461F (5 µH + 1 Ω) || 50 Ω. With the optional external capacitor CAP 10 it can be used for DO-160 and DEF STAN 59 as well.
The EuT is connected to the wing terminals at the front panel. The mains terminals are on the backside.
