Measurement support system CAT-400 system
An antenna positioner and a turntable that are controlled by one controller via optical cable between measurement room and anechoic chamber. A servomotor mounted on the power section is allowing to achieve high accuracy.
antenna positioner
By mounting the servo motor, the antenna positioner is more accurate (1 mm unit) and strong. We also offer tilt (boresight) attachment options up to 1 GHz and boresight antenna positioners that can be used for tests above 1 GHz to meet the needs of boresight antenna positioners. Please contact us for more information.

controller CAT-400
The CAT 400 is a smart, advanced controller with a touch panel operation unit, and it is designed as an expandable product that can control the antenna positioner and the turntable, and also can control the tilt operation as an option. By connecting the optional remote control(CR-3), it can easily permit to control the up/down motion of antenna positioner and polarization, and rotation of turn table at hand.
