The manual part of these tests involved connecting the CCU to the test unit and taking hundreds of reading on a Logic Analyzer. On average, it took about 42 hours for a complete set of tests if no problems were encountered. The manual for these tests had “hand drawn” wave forms in it and cable connections were many times redundant configurations.
