Abstract
A measuring deviceincludes a DUT scanning mechanismthat is provided in the OTA chamber, includes a biaxial positioner which can be rotationally driven by drive motorsand, and rotates a DUTto sequentially face all preset directions of a spherical coordinate system; an integrated control devicethat measures the DUTat each measurement position corresponding to each of the all directions; and a rotation speed management control unitthat controls a rotation speed of the drive motorsandat 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 DUTis measured.
