RS105 NEMP Test System

Montena

 


BROCHURE: MONTENA PRODUCTS  |  NEW HPD SIMULATOR


The MIL-STD461, respectively IEC 61000-4-25, is applicable to equipment or subsystems located outside a shielded facility. The RS105 NEMP test method describes a transient electromagnetic pulse of up to 50 kV/m, double exponential wave with a rise time in the nanosecond range, that is applied to the equipment under test (EUT) at least 5 times. The EUT should not exhibit any signs of performance degradation.

Montena designs and manufactures bounded wave NEMP (Nuclear Electromagnetic Pulse) / HEMP (high altitude NEMP) simulators for radiated susceptibility tests. Mobile systems for indoor use and fixed simulators for outdoor installations have been developed and marketed since 1998.

The simulator setup mainly consists of a high voltage pulse generator connected to a transmission line ended with distributed resistors. A voltage monitor and various field sensors are used to measure the generator output and the electric and magnetic field strengths. The resulting signals are transmitted via fibre optics or coaxial cables to the oscilloscope.
