SIGnal Workbench is an Ideal Platform for Engine, Turbomachinery and Other Vibration Test Applications

ATLANTA -- Concurrent (NASDAQ:CCUR), a leading provider of time-critical Linux[R] operating systems, integrated software and computer solutions for mission-critical applications, today announced that four of its SIGnal Workbench[TM] test systems have been installed by IHI Corporation (IHI), the premier manufacturer of jet engines in Japan.

"The SIGnal Workbench platform performs multiple-channel FFT and Campbell analysis for our noise and vibration test applications," said Mr. Nobuya Minagawa, General Manager, Measurement Engineering Group, Advanced Technology Department, Aero-Engine & Space Operations, IHI Corporation. "SIGnal Workbench's ease of use and real-time performance have dramatically reduced our development and test schedule while contributing to overall efficiencies and aircraft engine quality."

SIGnal Workbench is Concurrent's recently-introduced solution for advanced, high-cycle fatigue testing applications. This fully-integrated software and hardware platform, SIGnal Workbench features:

* SignalBoss[TM] software from Experimental Design & Analysis Solutions, Inc. (EDAS), a comprehensive graphical application suite offering quick, easy, step-by-step instruction through the vibration testing process.

* Concurrent's RedHawk[TM] Linux real-time operating system for the fully-deterministic, guaranteed performance needed in high-performance, time-critical test applications.

* A Concurrent iHawk[TM] real-time computer platform custom-configured to test applications needs.

* One or more 32-channel Sigma-Delta analog input boards supporting a rate of 200 kilosamples per second per channel. Other simultaneous sampling analog input cards are also available.

* Optional four-channel signal conditioning modules that provide programmable transducer interface circuitry. Each channel includes a configurable current/voltage output source and a fault-protected programmable gain amplifier.

"We very pleased with IHI's selection of SIGnal Workbench. We also look forward to working with our technology partner, EDAS Inc., to continue to serve IHI and all our customers with advanced, economical solutions for vibration test," said Ken Jackson, Vice-President of Concurrent Special Systems.
