T-DualScan is an innovative planar near-field system that offers the best compromise between accuracy, flexibility and measurement speed. The tower positioner can rotate 180° to switch easily from the single-probe set-up (0.8 - 110 GHz) to the multi-probe set-up (0.8 - 18 GHz). T-DualScan can also be offered as an upgrade to existing installations.
Measurements can be performed in both continuous wave and pulsed mode. In the case of phased array antenna measurement, the system utilizes the real time controllers to control and synchronize the measurement system with the device under test.
The probe array system calibration allows for both consistency in amplitude and in phase as well as the radio-electric axis alignment of each probe. The calibration procedure consists of the rotation of a reference antenna along a roll axis in front of each probe. This is performed with a dedicated calibration arm supporting the reference antenna and its motorized roll axis. Mounted on one of the linear axes of the scanner, the calibration arm moves linearly to position the reference antenna in front of each probe of the array.
The DUT positioner is composed of standard ORBIT/FR positioning equipment that can be adapted to the spe-cific requirements of each customer. An innovative DUT positioner base allows for easy movement of the DUT positioning equipment, thanks to four air cushion pads. To move the DUT linearly, a simple air hose is connected to the four air pads' central manifold, and the system is slightly elevated on a thin air cushion (0.08 mm). The system has virtually no friction and can be moved simply by pushing it to its new position.ASK A QUICK QUESTION
