eagle test systems ETS-88

The ETS-88 is an optimal test platform for testing a wide variety of devices including: simple analog, high precision, high voltage, high current / power, automotive, video, audio, complex mixed-signal, as well as emerging power processes like SiC and GaN. The ETS-88 test system hardware is designed to provide independent floating resources per site to avoid resource sharing across sites while improving site-to-site isolation and measurement accuracy.


Multi Test Head design supports high parallel test efficiency, capable of testing up to four unique DUTs per test system in 1 square meter of floor space. Each test head offers up to 72 analog channels and up to 32 digital channels (66/132 MHz).

Industry leading EV software operating from a dual quad core CPU controller supporting both index parallel and multi-site test.

Fully compatible with ETS’s line of Digital and Floating SmartPin™ Resources.

Test system PC runs on familiar MS WindowsTM operating system and executes programs from C++ Visual StudioTM environment.

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.

Instrument Options

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. 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: EV and EV-MST. Referring to multi-sector technology, EV-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.
