BHUNTSVILLE, AL -- October 11, 2002 -- Teradyne's [NYSE: TER] Assembly Test Division (ATD), a global leader in electronics testing and production solutions, today announced the introduction of the Bi4-Series™ of serial bus test instruments (BTI), the first "synthetic" instrument capable of assuming a wide range of serial bus protocols required in military and aerospace test environments. Teradyne will introduce the Bi4-Series™ of serial bus test instruments to the public at the AUTOTESTCON conference focused on automated test and related technology for military, government and aerospace applications in Huntsville, AL on October 14, 2002.

The Bi4-Series BTI possesses built-in "morph-ability," to assume the bus protocol language of serial communications buses used in operational or factory environments. Because it is able to both emulate and test serial buses, it eliminates the need for a broad range of individual, protocol-specific test instruments, providing a convenient solution that reduces the overall cost of test, and simplifies the logistics involved in setup and deployment of multiple test systems.

"The BTI provides our customers in the military and aerospace markets with an extremely flexible and convenient solution for bus testing and emulation at all levels of test," said Stephen Fairbanks, marketing manager of ATD's Mil/Aero business unit. "This type of product innovation will significantly help in our customers drive to reduce test costs."

About the Bi4-Series BTI

Teradyne's Bi4-Series is the industry's first instrument designed specifically to address the unique requirements for real-time bus test and emulation at functional test. Each BTI has 4 independent bus modules that support MIL-STD-1553, MIL-STD-1773, TIA/EIA-RS-232, TIA/EIA-RS-422, TIA/EIA-RS-485, H009, ARINC 429, and more. There is no need for external electronics, custom circuitry, or compromises of any kind. With an innovative load-and-forget programming environment, native support for popular buses, and the flexibility to emulate custom buses or variations of standard buses, each of the four bus modules provides the option to emulate a wide variety of serial bus communications and test those protocols, at any time.
