 These tests determine whether equipment will operate within performance specifications when the equipment and its interconnecting wiring are exposed to a level of RF modulated power, either by a radiated RF field or by injection probe induction onto power lines and interface circuit wiring.

Two test procedures are used: 1) From 10 kHz to 400 MHz, the equipment under test (EUT) is subjected to RF signals coupled by means of injection probes into its cable bundles, and 2) for frequencies between 100MHz and the upper frequency limit, the EUT is subjected to radiated RF fields. There is an intentional overlap of the tests from 100 to 400 MHz.

Equipment with special signal, frequency, modulation, or bandpass characteristics may require test variations as specified by the applicable performance standards.

The result of these tests can be used to determine equipment response to various RF threats such as HIRF, T-PEDs, and installed system's emissions, and to permit categories to be assigned defining the conducted and radiated RF test levels of the equipment.

These tests are sufficient to obtain environmental qualification for radio frequency susceptibility of the equipment. Additional tests may be necessary to certify the installation of systems in an aircraft dependent on the functions performed.
