Description
Overview
The main application of the unsymmetrical single path AMN (artificial mains network) NNBM 8124-200 is the measurement of interference voltage in vehicles, aircrafts and ships in the HF-VHF range 0.1 – 150 MHz. The NNBM 8124-200 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 10-200 it can be used for DO-160 and DEF-STAN-59 as well.The continuous current rating is 200 A, for short time more than 280 A are possible. The EuT is connected to the wing terminals at the front panel. The mains terminals are on the backside.
