Overview
The Turn Device TD 1.5-2kg is especially designed for mobile telephone measurements. Different sized mobile telephones can be mounted on the mounting bracket made of Rohacell.
The TD 1.5-2kg is usually mounted onto a turntable to have both 360° vertical and horizontal rotation for 3D measurements.
Together with the turntable the system performs three-dimensional over-the-air radiation measurements on handheld wireless devices, mainly mobile phones. The measurement height is fixed – standard is 1.5 m above floor level. Other heights are available upon request.
The Turn Device, with the exception of the drive unit, is fabricated from plastic (Rohacell, PVC and reinforced fibreglass). Metal parts are located only in the base plate and the drive mechanism (max. 0.3 m above ground level).
The IEEE 488.2 (GPIB) bus provides an additional control option for all functions, when operated with the SCU/MCU or NCD Controller.
