Automatic production test equipment (APTE) for the B-2

The automatic production test equipment (APTE) was developed to provide an integrated capability for seven test conductors and one chief test conductor to interactively test a system with bus architecture. Each test conductor has access to 35 data buses and a centralized database to generate stimuli and monitor responses from the vehicle subsystem. The chief test conductor resolves potential resource conflicts and monitors critical parameters for safety considerations. Test program development is accomplished using windows, graphics, and a menu-driven environment to eliminate the need for extensive operator training and software language skills
