T- DualScan T-DualScan
I T-DualScan 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.

I T-DualScan DUT positioning system (optional) H DUT positioning system with air cushion for easier movement. Single-probe The DUT positioner is composed of standard ORBIT/FR positioning equipment that can be adapted to the specific requirements of each customer. An innovative DUT positioner base allows for easy movement of the DUT positioning equipment, thanks to four air cushion pads.
