CT840a Large 2D-Turntable LANforge Chamber

The CT840a RF Chamber is used to isolate WiFi and other RF equipment from the outside environment. This allows more repeatable testing options. In addition, when combined with RF attenuators and WiFi traffic generators, chambers can be used to create emulated mesh and mobility scenarios, including the TR-398 automated test suite. The CT840a offers 85+ dB of isolation for excellent performance even in noisy environments, 2D turn-table for antenna orientation testing, and other features expected in quality chambers.
