This system is designed for EMC anechoic chamber radiation testing. In standard configuration, it includes: 1 × GETT-2000 turntable, 1 × GEAM-4600 antenna mast, 1 × GEC-3 controller. The turntable, antenna mast, and controller communicate via fiber optic systems to achieve coordinated motion control. By modifying the controller program, the turntable or antenna mast canalso operate i ndependently with the controller for individu al motion control .

GETT-2000 Turntable System

The GETT-2000 turntable features a flush-mounted designwith its working surface level with the chamber floor. It's rotating platform has a diameter of 2 meters and is suitable for chambers with a quiet zone area of 3.14 m2.

GEAM-4600 Antenna Mast System

The GEAM-4600 Antenna Mast is a dual-pole system with tilt functionality. It features an effective vertical travel range of approximately 4.6 meters. The mast's elevation and tilt movements are motor-driven, while antenna polarization switching is achieved through pneumatic cylinder actuation. All electrical components, including motors, are shielded and enclosed within a conductive-coated metal drive housing located at the mast base.

GEC-3 Controller

The GEC-3 controller integrates PLC, touchscreen, fiber optic, and LAN communication functions, capable of controlling all GE-branded turntables and antenna masts. It features RJ45, USB, and RS232 interfaces, supports TCP/IP communication protocol for seamless PC connectivity, and runs on an Android-based touchscreen supporting multilingual operation environments and customizable HMI interfaces.
