Electromagnetic Compatibility

CM ATR chassis surpass MIL-STD-461 EMI/EMC testing, carried out according to the stringent criteria requirements of the US Navy and Air Force. Our ATR products have passed the most restrictive EMI levels for Military Transport Aircraft (>25m), Military Fighters (<25m) and Military Helicopters. EMI levels exceed Military & Aerospace requirements.
