At NTS, our experience encompasses more than 50 years of electromagnetic compatibility testing for clients in the aerospace, aviation and other related industries. We maintain fully equipped electromagnetic interference testing facilities in Illinois, Arizona, California, Massachusetts, Texas and New Jersey. With the combined expertise of our team, it’s easy to identify the regulatory challenges your organization faces, and develop a comprehensive testing program that ensures your challenges are met.
Of particular concern to avionics manufacturers, high intensity radiated fields (HIRF) are any combination of electrical and magnetic interference strong enough to potentially impact the performance of a device in close proximity to it. HIRF is divided into three frequency bands, and each can affect airplane electronics in different ways:
HIRF testing is a form of EMC testing applicable to equipment that is subject to extreme electromagnetic environments and/or mission critical equipment whose failure would be hazardous to human safety.As greater dependence is placed upon an aircraft’s electrical and electronic systems performing functions required for safe flight operations, concern has increased for the protection of these systems. Concern for the protection of electrical and electronic systems in aircraft has increased substantially in recent years due to:
NTS testing labs are fully equipped to provide HIRF and other electromagnetic interference testing for some of today’s most demanding clients. We are the nation’s largest independent product testing and standards compliance organization, with a long history of meeting the needs of military contractors, avionics manufacturers and more. We can ensure you meet the requirements for any of the variousspecifications which include HIRF certification, such as:
HIRF certification typically involves measuring transfer functions to estimate the potential effects of electromagnetic interference (EMI) on an aircraft. We employ a variety of tools and techniques to produce accurate testing that is fully compliant with all required specifications.
Our reverberation chambers and state-of-the-art amplifiers achieve greater that DO-160 Category L levels from 200 MHz to 18GHz. Test frequecies as high was 40 GHz are now possible at our Rockford, IL, Boxborough, MA, Fullerton, CA, Plano, TX and Tempe, AZ locations. The chambers large usable test volume allow for testing multiple-LRU systems. With field densities capable of achieving peak fields up to 15,000 V/m, these chambers are also drive stand-adaptable and can be mated to a motor drive for rotating equipment.
