Classification: CPC G  H | IPC G  H

Claim 0:
1. A mobile terminal testing device comprising:
a positioner that includes an azimuth axis and a roll axis each of which can be rotationally driven by respective drive motors, and rotates a mobile terminal which is a device under test to sequentially face a plurality of preset directions of a spherical coordinate system using a center of the spherical coordinate system as a reference point;
a simulated measuring device that is connected to a test antenna; and
a processor configured to:
control the simulated measuring device to perform a measurement operation of transmitting a test signal from the test antenna to the mobile terminal, receive a measured signal transmitted from the mobile terminal by the test antenna, and measure a specific measurement item related to the mobile terminal based on the received measured signal at each measurement position corresponding to each of the plurality of directions; and
control a rotation speed of the drive motor to be a rotation speed which is lower than a maximum rotation speed and to reduce a time required for the positioner to move at a unit movement angle relative to a prior rotation speed, from a first measurement position where the measurement is completed to a second measurement position where a next measurement is to be performed by the unit movement angle during the specific measurement item is measured.
