Claim 12:
13. A mobile terminal testing method for performing a test of a mobile terminal using a mobile terminal testing device including
a positioner that is provided in an internal space of a radio anechoic box,
rotation control means for executing, with respect to the positioner, first rotation control that causes the mobile terminal, which is a device under test, to sequentially face each of first 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, and 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,
measurement control means for executing a processing step of measuring reception power by receiving a radio signal from the mobile terminal using the test antenna in the internal space by executing the reception sensitivity test for each of the first orientations and the second orientations, and
peak power measurement means for executing a processing step of measuring maximum reception power as peak power based on the measured reception power,
the mobile terminal testing method comprising:
as the processing step of measuring the maximum reception power as the peak power,
a candidate selection step of selecting, as peak power candidates, the first orientation having reception power within a range of a predetermined power width from the maximum reception powers among the reception power measured for each first orientation; and
a determination step of measuring the reception 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.
