1. An apparatus for wireless testing using automated test equipment (ATE), the apparatus comprising:

  • a test interface adapted to be coupled to an electronic device and configured to transmit data to and receive data from the electronic device;

    a test generator configured to drive the electronic device through the test interface to vary a beam direction of a test signal of the electronic device while maintaining a static test position of the electronic device;

    a test module configured to determine a plurality of transmit values of a transmit parameter, based on the test signal wirelessly received from the electronic device using at least one static antenna for receiving the test signal, wherein each transmit value of the transmit parameter is associated with a different beam direction; and

    an analysis module configured to provide an assessment of a plurality of transmit paths of the electronic device based on the plurality of transmit values, wherein each transmit path is associated with a different beam direction, and wherein the analysis module is further configured to determine one of a gain parameter and a phase parameter for each transmit path based on the plurality of transmit values.
