INTERNAL LINE REPLACEABLE UNIT HIGH INTENSITY RADIATED FIELD DETECTOR

摘要

Various embodiments for detecting a High Intensity Radiated Field (HIRF) in a Line Replaceable Unit (LRU) are provided. The internal detector may be used to test EMI filter pin connectors of a closed LRU. For example, a method comprises setting a selecting switch to a test connector position, thereby connecting a RF signal generator to a testing connection cable. The method further comprises causing the generator to generate a test signal as input into the testing connection cable, and determining if an internal HIRF detector has detected the signal. If the signal is detected, the method further comprises, for each EMI filter pin connector in the LRU, switching the selecting switch to a corresponding test cable coupled to an EMI filter pin connector, causing the generator to generate the test signal as input into the corresponding test cable; and determining if the detector has detected the signal.

1. A method for testing EMI filter pin connectors of a closed line replaceable unit comprising:
setting a selecting switch to a test connector position, thereby connecting a RF signal generator to a testing connection cable, the testing connection cable being attached to a test connector of a line replaceable unit; causing the RF signal generator to generate a test signal as input into the testing connection cable; determining if an internal high intensity radiated field detector has detected the test signal, wherein if the test signal is detected, the method further comprises, for each EMI filter pin connector in the line replaceable unit, switching the selecting switch to a corresponding test cable coupled to an EMI filter pin connector; causing the RF signal generator to generate the test signal as input into the corresponding test cable; and determining if the detector has detected the test signal, wherein if the test signal is detected, the associated EMI filter pin connector coupled to the test cable is not functioning properly.
