ANAHEIM, Calif.--(BUSINESS WIRE)--March 31, 2003

Features Safe, Accurate Testing of Low-Voltage Technologies at Affordable Price

Teradyne's (NYSE: TER) Assembly Test Division, a global leader in electronics testing and production solutions, announced today at the APEX tradeshow in Anaheim, California, the immediate availability of the TestStation LH(TM) in-circuit test (ICT) system, a new lower-cost, small footprint, feature scalable, version of Teradyne's popular, award winning TestStation 12X(TM) product family.

The TestStation LH features the voltage accuracy and backdrive current measurement embedded in Teradyne's SafeTest(TM) protection technology to provide accurate, reliable, and safe powered-up testing of today's new low-voltage technologies, ensuring product quality and reducing overall product costs. Its scalable feature set allows customers to get superior TestStation(TM) technology at a significantly reduced price.

"The TestStation LH system provides electronics manufacturers with a very cost-effective, powerful and flexible in-circuit test solution," said Roy McKenzie, ICT product marketing manager at Teradyne. "It is feature-scalable, can be configured with anywhere from 256 to 4096 test pins, and is capable of safely and accurately testing low voltage technologies. I can say with all confidence that the TestStation LH system is the best value for in-circuit test in the industry."

About TestStation LH

The TestStation LH in-circuit test system provides electronics manufacturers with the same advanced test capabilities of the TestStation product family in a smaller footprint, lower priced version.

System Features:

• SafeTest protection technology - allows safe powered-up testing of low-voltage devices
• Configurable from 256 to 4096 test pins - fits requirements for most test applications
• 52 percent smaller than TestStation LX models - saves valuable manufacturing space
• Feature scalable - perfect for today's needs, fully upgradeable for future requirements
• Turn-key programming solutions - for ease of use and accelerated time to production
• New design - for improved reliability
• Compatible with most GR228X(TM)/TestStation programs and fixtures - preserves test investments

About SafeTest Protection Technology

SafeTest protection technology is founded on the combined strengths of Teradyne's patented UltraPin(TM) digital pin electronics and built-in TestStation software features. This powerful combination of technologies permits accurate, reliable, and safe powered-up testing of today's new low-voltage technologies, ensuring product quality and reducing overall costs. This is achieved through the reduction of false failures that lead to unnecessary rework and the elimination of voltage conditions that could lead to field failures and their resulting warranty and liability costs. SafeTest protection technology features:

• The most accurate ICT driver/sensor pin in the industry for safe test of low voltage technologies
• Closed loop driver capable of delivering accurate programmed voltages even under backdriving and fault conditions
• Backdrive current sensing identifies unreliable and potentially harmful tests
• Programmable backdrive current and duration thresholds allows programmer control of backdrive current and duration
• Automatic driver verification that each pin achieves its programmed threshold
• Per-pin programmable logic thresholds and timing means no test compromises because of tester limitations
• Specialized digital controller quickly executes test vectors to minimize backdrive duration
• Multi-level digital-isolation software prevents dangerous voltage spikes
