Omega Mixed-Signal Test System

Introduction

The Omega from MiNT System is a full featured Mixed-Signal Test System.  Omega features a highly modular architecture that permits the user to configure the system for specific test applications and easily expand the system to meet future testing needs.

 

Flexible

Omega is designed to provide a high-speed test capability for a wide variety of analog and mixed signal semiconductor components. Instrument modules are designed for automotive, industrial, consumer,  power, communication, and computer device testing. It is optimized for use in engineering as well as production test facilities with handler and prober interfaces.

Economical, reliable, and easy to use

The small footprint and low power consumption makes Omega the right choice for the economy-minded test manager.  Highly accurate and reliable, the Omega system is easy to operate, program and maintain.  The system features easy-to-learn programming techniques, using datasheet and parameter tables to speed new test program development.

When accuracy in mixed-signal testing and low cost-of-test are important, Omega is the solution.

Hardware Features

The Omega supports up to 29 instruments in the mainframe and additional modules inside the test-head enclosure.  Pico Ammeter and Time Measurement modules are available for load-board mounting.

The system bus structure features an Opto-Isolated System Data Bus and separate Calibration and Instrument Bus structures.

Multiple instruments may be installed in the Omega for larger and more complex test applications.

Additional instrument functions may be added using the IEEE-488 interface.  Interfacing to the application load board is simplified by using load-fixture relays and the system control bits.

The Omega system features automatic calibration hardware and software that ensures the test accuracy is maintained.  The calibration module is removable for easy re-calibration to NIST standards.

Diagnostic programs rapidly pinpoint system faults and helps to minimize repair times.

The remote test head is easily moved and docked to most handlers and prober systems.

Software Environment

Test Programs are developed in Microsoft C++, operating in the Windows environment. Device parameters are entered using a datasheet format for quick and easy program development and editing.

The Test Program Debug Facility speeds the testing and debug of new test programs, lowering development costs.

Most software and hardware functions are controlled through the use of a Graphical User Interface (GUI) using multiple windows.

Test Programs are compiled for faster execution and less test time.

High-Speed Communications with System Instruments and Modules is accomplished using the dedicated instrument bus system.

Off-Line Test Program Development is  accomplished on any PC-based computer system capable of supporting Windows.

Data analysis is enhanced using the software link to Excel spreadsheets and graphical analysis tools.

Test Program Set-Up files are used for added security and error-proof operations.

Operation

The Omega Mixed-Signal Test System is easy to learn and use.  The Window platform provides the control for system operation, test-program development, and data collection and analysis.  The Operating System (SYSOP) provides the highest speed control of the system instrument set and for high-speed data collection.  Separate control windows are available for Operators, Administrative, and Engineering personnel, providing test-floor control and security. Simple setup files speed the changeover of the Omega from product to product.

A full range of stimulus and measurement instruments are available for the Omega system.  Digital Voltmeters, Voltage and Current Supplies, Voltage Reference Supplies, Function Generators, Counter, Timer, Phasemeter, Audio Voltmeter, Arbitrary Waveform Generators and Digitizers, and up to 16 channels of digital pin electronics for mixed-signal control and measurements.

Programming

Ease of test program development and test program control is a standard feature of the Omega Test System.  Programming may be performed on the test system or on any PC computer capable of supporting the Windows and the Microsoft C/C++  program development environment.

The programmer enters device test parameters into easy to read and understand tables and “spec sheets.”  Instrumentation controls are easy to understand and easy to write using the Microsoft C with spec sheet functions.  Cutting and pasting of functions allows the programmer to create new test programs easily using standard test routines.

The Test Tree GUI allows quick selection of desired tests and changes to test flow. Quick editing of values is accomplished through Parameter Tables.

Data Analysis

The collection and display of data is simplified through the use of a tool set designed as an integral part of the operating system.  Data collected during test execution are available in several forms and are easily analyzed on- or offline.  Data files can be downloaded to other network computers where data analysis may be performed.  Online tools includes a histogram, wafer map, and 3D composite wafer map. Analysis tools are easy to setup and use since most functions are already programmed and ready to use for the most common data display formats.  Microsoft Excel software is included with the operating system for offline custom data analysis.
