DNB develops RS105 Test Capability

This difficult and challenging MIL-STD 461 susceptibility test generates a simulated electromagnetic pulse with a peak field strength of 50,000 V/m.

It’s used to verify the ability of an equipment under test (EUT) to withstand a transient electromagnetic field associated with a nuclear detonation. This test may be applicable to equipment and subsystem enclosures when the equipment or subsystem is located externally to a hardened (shielded) platform or facility in vehicles, on board ships and aircraft.

DNB Expands

DNB has expanded! In response to industry demand, we have increased our capacity significantly in our EMC and Environmental test areas. In our new 28,000 square foot, facility we have installed 9 new EMI chambers. And the centerpiece of our new facility is our LARGE (30’ x 25’ x 14’) Mode Tuned Chamber and associated 10KW TWT Amplifies, which can produce field strengths up to 10,000 V/m. We also have six 20’x 20’s , one 20’ x 24’, and one 24’ x 30’ chamber.
We have also significantly increased our capacity in our Environmental test area. Our new facility increases our capabilities in the areas of Temperature, Humidity, Salt Spray, Altitude, Decompression, Vibration, and Shock testing.
