00L-3 Cincinnati Electronics is a world leader in providing high intensity radiated field (HIRF) and aircraft attenuation test services. HIRF testing is a form of radiated susceptibility testing
which is required in the certification of flight essential avionics systems. The primary attributes of HIRF, with respect to this type of testing, are elevated test levels and pulsed modulation requirements. The HIRF testing intent is to simulate high RF peak pulsed and average field environments typical of radar installations.
00Frequencies from 10kHz to 40GHz are offered with continuous
scan capability. L-3 CE's downloadable data sheets provide the typical HIRF pulsed and average levels; additional duty cycles may be available on request. A system must not exhibit degraded performance or sustain damage when subjected to HIRF fields while operational to be considered compliant with the certification requirements.
00L-3 Cincinnati Electronics test facilities also provide aircraft and engine nacelle attenuation testing services. The attenuation measurements are performed to quantify the bench HIRF environment. The attenuation of the nacelle or aircraft measured is subtracted from the external HIRF environment to determine bench test levels.
