NORTH READING, MASSACHUSETTS - March 30, 2001 - Teradyne, Inc. (NYSE: TER) announced that its Ai7 32 Channel Analog Measurement Board has received the 2000 "Best New VXI Product of the Year" award from VXIBus Newsletter. The annual award was presented by Fred Bode, editor-in-chief of VXIBus Newsletter, in the November edition of the publication.

Teradyne's Ai7 Series employs unique tester-per-pin analog testing architecture to provide high-throughput testing for complex mixed-signal modules. The 32-channel instrument performs real-time functional test with six independent test resources per channel, offering VXI system integrators unparalleled flexibility to create test programs that emulate as-used configurations. With a total of 192 instruments simultaneously available, the Ai7 Series reduces no-fault-found conditions, increasing product reliability while ensuring high overall throughput.

As Bode noted, he chose the Teradyne Ai7 "...because it demonstrated some very interesting 'Outside-the-Box' thinking.... This takes a page from digital pin-based electronics, where you want to make simultaneous measurements on a large number of channels. Traditionally, analog instruments were too expensive and too large to consider this approach, so automatic test systems were forced to switch the instruments sequentially to different pins and make a sequence of measurements, thus slowing overall throughput. Now Teradyne appears with a 32-channel, single-slot VXI module that has 6 measurement instruments per channel, for a total of 192 instruments."

Steve Fairbanks, Ai7 Series Product Manager, added, "The Best New VXI Product award is great honor for us. We are grateful for the recognition of our success in designing and developing robust, leading-edge products that continue to meet the demanding test requirements of our customers."
