Shielded Room Make-over

Adding State-of-the Art RF Test Capabilities to Existing Test Systems

A company’s test requirements change over time, and some companies find themselves with small, shielded rooms that are underutilized. One such company was LS Research in Cedarburg, Wisconsin. After a facility expansion including a new state-of-the-art 5 meter anechoic chamber, LS Research looked to re-purpose an existing 10' x 10' x 24' (3m x 3m x 7.3m) shielded room in order to add a dedicated Antenna/OTA measurement system to their testing services offering.

Utilizing the distributed axis spherical positioning system from the popular Model 3100 Wireless Test Lab, The Howland Company provided LS Research with a complete OTA test system that is compliant with the CTIA Test Plan for OTA Measurements. The test system included a dual axis positioning system, dielectric device under test (DUT) support, dual polarized measurement antenna, and Howland WTL software. LS Research provided the RF instrumentation and the microwave absorber for the chamber. Engineers from The Howland Company installed and tested the complete system before turning it over to LS Research engineers. The completed system operates from 700MHz to 10 GHz and is capable of automated antenna and OTA wireless device measurements.

Although the current system is configured for small wireless devices, in the future it could be upgraded to test large wireless devices such as a connected appliance. Overall, this addition to their testing services has provided LSR the means to provide their customers with more detailed spherical antenna patterns, while also dramatically improving the efficiency of the test personnel thanks to the system’s automation and powerful software.
