Abstract
A measuring device 1 includes a DUT scanning mechanism 56 that is provided in the OTA chamber 50, includes a biaxial positioner which can be rotationally driven by drive motors 56f and 56g, and rotates a DUT 100 to sequentially face all preset directions of a spherical coordinate system; an integrated control device 10 that measures the DUT 100 at each measurement position corresponding to each of the all directions; and a rotation speed management control unit 18b that controls a rotation speed of the drive motors 56f and 56g at a rotation speed which shortens a time required for the movement in a case where the biaxial positioner is moved at a unit step angle from a measurement position where the measurement is completed to a measurement position where next measurement is performed during the DUT 100 is measured.
