FAST Key Benefits
• 80% reduction in test times
� compared to manual test execution
• Increased Efficiency
� Developers can concentrate on problem solving activities rather
than test execution and documentation
• Improved Product Quality
� More units tested and more tests executed.
� More time to find and resolve issues during the design phase
• Automatic Results Documentation
� High quality results documents automatically generated

(over temperature and voltage)
FASTManualProject 3G NodeB
Example: Measured times for a 3G basestation (NodeB)
Note: Manual times shown do not include time for documenting results.
FAST automatically produces a set of formatted results.
Common Test Platform (CTP)
• Benetel’s core ATE product
• Developed over more than 7 years
• A Test Management, Test Sequencer and User
Management platform developed to optimise manufacturing test times and test reliability
• Allows cost effective customisation to test different
customer products
