Abstract: A method for evaluating radio performance of a device under test (DUT) comprises the following steps. A first set of points, a second set of points and a third set of points are defined to locate on a sphere surrounding the DUT. A signal power of the DUT is evaluated at the first set of points to identify a first region related to the first set of points. Candidates of the second set of points are selected based on the first region. The signal power of the DUT is evaluated at the candidates of the second set of points to identify a second region related to the second set of points. Candidates of the third set of points are selected based on the second region. The signal power of the DUT is evaluated at the candidates of the third set of points to identify a beam peak.
