| Abstract: | The test requirements of non avionic monitoring processor (NAMP) including the function, composition, BIT andATE test interface were introduced. The auto test principle circuits and test technological process for NAMP based on ATEsystem platform were also given. BIT and ATE combination test technology was applied to realize the functions of auto testand faults diagnosis was accomplished by fault tree diagnosis. The equipment performance was validated by fault injectionand application in the following respects, full coverage of test content, accurate fault diagnosis and high fault isolation rate. |
