1. A mobile terminal testing device comprising:
a positioner that is provided in an internal space of a radio anechoic box; and
measurement control means for measuring reception power by receiving a radio signal from a mobile terminal, which is a device under test, using a test antenna in the internal space, wherein
the measurement control means includes
rotation control means for executing, with respect to the positioner, first rotation control that causes the mobile terminal to sequentially face each of orientations regulated by a predetermined step interval of a spherical coordinate system, and second rotation control that causes the mobile terminal to sequentially face each of second orientations regulated by a step interval finer than the predetermined step interval,
reception sensitivity test execution means for transmitting a test signal from the test antenna, repeatedly performing a reception sensitivity test of receiving a signal under measurement transmitted from the mobile terminal which has received the test signal using the test antenna and measuring a throughput based on the signal under measurement for each of the first orientations and the second orientations while changing an output level of the test signal non-linearly, and calculating reception sensitivity when the measured throughput satisfies a predetermined throughput measurement end condition, and
peak power measurement means,

reception power is measured for each of the first orientations and the second orientations by executing the reception sensitivity test for each of the first orientations and the second orientations,
the peak power measurement means measures maximum reception power as peak power based on the measured reception power, and
the peak power measurement means includes
candidate selection means for selecting, as peak power candidates, the first orientations having the reception power within a range of a predetermined power width from the maximum reception power among the reception powers measured for each first orientation, and
determination means for measuring the peak power for each second orientation by executing the second rotation control on a region within a predetermined range around the each of first orientations corresponding to each of the peak power candidates, and determining the peak power based on a measurement result.
