Grand Opening Showcases Reverberation Chamber Gift

Stillwater, Oklahoma, October 3, 2007 – Oklahoma State University held a grand opening of its new University Multispectral Laboratories featuring ETS-Lindgren's recent gift of a SMART™ 80 reverberation chamber valued at $275K. ETS-Lindgren President Bruce Butler noted the company has a long-standing history of partnering with universities to further science and technology. "The gift of this chamber enables OSU to offer a host of educational and testing capabilities that did not exist before," he said. "With the commitment of Chuck Bunting, associate professor of electrical and computer engineering, OSU can be a national leader in the fields of electromagnetic testing and education. As we continue our respective R&D efforts with reverberation chambers, we intend to collaborate with OSU and together move this technology forward."

OSU will use the reverberation chamber to evaluate the emissions and immunity of electronic devices in the frequency range of 80MHz to 18GHz. Reverberation chambers are commonly used for EMC testing in government, automotive, avionic and medical industries. Based upon technology initially developed with the advent of microwave ovens, these specialty chambers "stir" radio frequency waves and allow quick, cost effective radiated susceptibility and emissions testing. Benefits include high field to input power ratios, homogeneous fields, and large test object size to chamber volume ratios.

Mark Mawdsley, ETS-Lindgren's Managing Director of Asian Operations returned to OSU, his alma mater, for the opening event and commented, "We have customers in Asia who are making great strides with testing in reverberation chambers. It's exciting to see the commitment of OSU to educate engineers in the US about the testing capabilities and advantages of reverberation chambers. We look forward to a long partnership with Professor Bunting and the OSU students and faculty."
