The ETS-88 multiple test head architecture provides the flexibility to reconfigure the test system using software control. The system is comprised of dual sector test head card cages for up to four sectors depending upon system configuration. Each set of sectors can be bridged together within the test head card cage on an application-by-application basis. The sectors can be configured to operate independently, running unrelated applications if desired, or can all be bridged together to expand the site count of multi-site applications.
The system is controlled using a multi-core PC to maintain isolation between applications. This control method lets you assign cores and test heads to applications for the greatest test efficiency, and provides the ability to support single site, multi-site, and I.P. applications from a common base platform.

The ETS-88 test system is a general purpose precision analog and mixed-signal test platform designed for high volume production testing of integrated circuits. The system is optimized for high throughput applications, with a fully integrated multisite software and hardware architecture. Following the Eagle tradition, the ETS-88 test system offers high precision and high accuracy test capabilities. Test speed is only of value if the results are trustworthy. As such, the ETS-88 test system provides both measurement speed and high accuracy, following the ETS tester tradition of providing high precision test capabilities with a robust assortment of available instruments such as V/Is, DC/AC voltmeters, digitizers, AWGs, digital pin electronics, and time measurement instruments, all optimized for multisite testing.

The ETS software development environment and tool set are truly one of the strongest attributes of the ETS-88 test system. The software tools are easy to learn and use, and are fully integrated into the Microsoft Visual Studio development environment. The complete test system command set is supported with automatic code generation tools (ACE™ and GrACE™). This means that users are not required to memorize command arguments and syntax. Graphical plotting tools are provided for simple point-and-click plotting of test-oriented waveforms. RAIDE™ (Rapid Access Interactive Debug Environment) makes it easy to view and change tester hardware settings.
ETS’s software provides a robust test development environment, offering customers an easy learning curve and uncommon productivity. There are two versions of the software: Eagle Vision (EV) and Eagle Vision MST (EV-MST). Referring to multi-sector technology, Eagle Vision MST allows users to replicate test programs across multiple test head sectors. The standard ETS-88 test system supports both software suites. Adding options, such as the AC-2500, may change which suite is supported.
