Anechoic Chamber Positioning System
Integrated turntable system,antenna mast system, and controller for EMC radiated testing.
Anechoic Chamber Positioning System
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 can also operate i ndependently with the controller for individu al motion control .
GETT-2000 Turntable System
The GETT-2000 turntable features a flush-mounted design with its working surface level with the chamber floor. Its rotating platform has a diameter of 2 meters and is suitable for chambers with a q uiet 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 mas t base.
