There were two variants of the new test system. One was for an older product line that utilized manual test, with an operator that connected/disconnected the UUT, and initiated the test. The other was an automated tester, integrated into a manufacturing machine. Both testers utilized custom fixtures (provided by the client), off-the-shelf NI measurement hardware (selected by Viewpoint), and custom test software (developed by Viewpoint). The software is configurable for both the manual test system and the automated test system.
