OTAP-10kg Over The Air Positioner

The state-of-the-art OTA Positioning system is especially designed to provide smooth rotations of test objects in both theta and phi axis. The OTAP system performs three- dimensional over-the-air-radiation measurements on handheld wireless devices or antennas.

- Measurements on mobile phones or antennas

- Independent rotations of both axes

- Variable speed adjustments in both theta and phi axes

- Possibility of operation in manual, semi-automatic and simultaneous remote control mode via IEEE 488.2 (GPIB bus) Ethernet with the controller FCU3.0 or NCD (IEEE 488.2, GPIB bus) using fibre optic control lines

- Manufactured with low reflective dielectric material

- Dielectric belt driven rotations

- Use of reliable, long-lasting and maintenance-free bearings
