Abstract
A method(s) of testing AN/ULQ-21 (Hydra) Circuit Card Assembly(ies) (CCAs), which involve providing software to perform automated tests on Hydra CCAs that make up the Hydra Countermeasures Set and employ commercial off the shelf equipment (such as signal generators, spectrum analyzer, Data Acquisition Device(s), oscillators, etc. as applicable depending on the test and CCA being evaluated).
Claims16
A method of testing a circuit card assembly (CCA) comprising:
- connecting an extender board to a CCA, said CCA having CCA memory;
- providing computer readable program code to cause a computer to verify the existence and connection of instrumentation;
- providing computer readable program code to cause a variable declaration to inform an electronic compiler a name and associated type of variable that data will be stored under;
- providing computer readable program code to cause said computer to store CCA card state parameters in a data structure;
- providing computer readable program code to cause said computer to write data to said CCA memory;
- providing computer readable program code to cause said computer to perform a hardware interrupt;
- providing computer readable program code to cause said computer to orient external test fixtures;
- providing computer readable program code to cause said computer to orient test equipment;
- providing computer readable program code to cause said test equipment to measure at least one aspect of CCA functionality;
- and
- providing computer readable program code to cause said computer to analyze said measurement of said at least one aspect of CCA functionality to determine whether it falls within a predetermined percent error of operating specifications.
