摘要： A system and method for testing wireless devices in a simulated a wireless environment is provided. RF modules for creating and receiving RF signals in a test environment are also provided. Features include RF isolation of a wireless device, including filtering signals on electrical paths to and from the device, and circuits to reduce undesired RF signals on such electrical paths, for example PCI bus paths. The system and method also include a test enclosure with isolation chambers with filtered electrical signal paths to allow testing of wireless devices inserted into the isolation chambers. This system and method also allows controlled testing of antennae diversity features of the wireless device.

摘要： An RF shielded enclosure that is configurable for a variety of testing requirements, yet still maintain proper RF isolation. User-installable modules that are specialized for the desired interface, ventilation or monitoring use can be installed on the enclosure to allow interfacing between a device under test installed inside the chamber and testing and controlling equipment outside the enclosure. The enclosure is easy to manufacture as a one or multi-chamber enclosure, allowing further flexibility for testing.
