1. A system for testing a device-under-test (DUT) over-the air (OTA), the system comprising:
a probe antenna configured to measure radiated fields from the DUT in a transmit test and to emit radiated fields to the DUT in a receive test by radiating electromagnetic waves upon active antenna elements of the DUT;
a rotational positioner configured to rotate the DUT about one or more orthogonal axes; and
a linear positioner configured to drive the DUT linearly along a first Y-axis and configured to drive the DUT linearly along a second X-axis perpendicular to the first Y-axis to stay within a quiet zone of the system.
