New Portable Test Cell Offers Fast and Convenient Wireless Testing

CEDAR PARK, Texas, February 23, 2009 – Drawing upon its extensive experience with state-of-the-art wireless test chambers, ETS-Lindgren now offers a portable RF shielded test cell, Model 5247, for making wireless device design verification and over-the-air performance measurements. At just 35.5” (90.17cm) long x 35.5” (90.17 cm) wide x 84” (213.36 cm) high with rolling casters, the test cell can be easily moved between locations for design verification, pre-certification, and production line measurement applications. The test cell is constructed with the same RF shielding and shielded door technology of ETS-Lindgren's popular chambers and offers performance of 80 dB over the frequency range of 700 MHz to 10 GHz.

Today, with one portable test cell, users can make preliminary measurements for both Over-The-Air (OTA) and Radiated Performance Testing (RPT) - the commonly referenced wireless device test standards issued by the CTIA - The Wireless Association™ and the WiMAX Forum™, respectively.

“We created this portable test cell to assist engineers with product design and development. It's really just a smaller version of our larger, full certification chambers,” says Dr. Michael Foegelle, ETS-Lindgren's Director for Technology Development. “Now, product designs and performance can be quickly verified for radiated power (TX) and sensitivity (RX) measurements before costly full certification testing. That helps companies get their products to market faster and less expensively.”

Model 5247 arrives ready for testing upon delivery. The test cell is fully lined with RF absorber and includes an EMCO brand, dual polarized horn antenna capable of both linear and circular measurements over the frequency range of 700 MHz to 10 GHz. An optional hybrid may be provided for circular measurements. The antenna is mounted on a quick change removable access panel to facilitate interchange with another antenna of a different frequency as needed. For added convenience, Model 5247 includes a populated connector panel with one SMA connector, three Type N connectors, one filtered D-sub 25-pin connector, a six-line fiber optic feed-through, and one ground stud. The shielded door provided uses compressible finger stock in a “knife edge” configuration. Two latch points on the door assure secure sealing while a single point handle enables one-hand operation.
