The HIRF Laboratory is a state of the  art facility for generating radiated electromagnetic environments for  testing the EM susceptibility, immunity and compatibility of flight  critical avionics.  It is located at NASA Langley  Research  Center in Building 1220. The test data acquired are used to study  avionic-upset and to characterize fault-tolerant systems. The lab  includes three reverberation chambers, TEM cells, high power amplifiers,  source generators, indirect lightning waveform and impulse generators,  and measurement equipment.  The lab has expertise in  reverberation chamber theory and operation, evaluation of portable  electronic device (PED) compatibility with aircraft systems, aircraft  coupling measurements and RF propagation, flight spectrum measurements  and EMI assessments, and EMI/EMC testing.  The lab is  currently supporting research in the Aviation Safety’s Integrated  Vehicle Health Management program, particularly HIRF and lightning  effects on metal and composite aircraft and wireless sensor  technologies.
