<p>A testing apparatus and method consisting of multiple measurement modules (10) having one or more circuit assembly boards (17, 18), two data/power connectors (14), and a target connector (16). The circuit assembly boards include electronics (19) for accessing and storing selected signal data emanating from a connected target system (56). Signal data is accessed from 1-128 target signal sources and sampled through two separate analog to digital channels (43). An on-board microcontroller (31) controls signal selection and data sampling rates and also provides for transfer of recorded data over a USB bus to a host computing device (59, 61). Using a proper testing application loaded onto the host computing device, each module (10) can be commanded to access and store representative data from a number of signal sources at each target system (56). Each module is connected to other modules and a host computing device to create a complete self-powered test access environment (58). With a proper testing application loaded on the host computing device, testing data may be acquired and analyzed for any selected target component system. The interconnectivity of the system as well as the data acquisition capability for each measurement module make diagnosing electronic component failures in an armored vehicle, such as a tank, much easier than prior manual fault isolation procedures.</p> |
