Abstract
An apparatus for wireless testing, wherein the apparatus includes a test interface, a test generator, a test module, and an analysis module. The test interface is coupled to an electronic device and is configured to transmit data to the electronic device and to receive data from the electronic device. The test generator drives the electronic device through the test interface to vary the beam direction. The test module determines 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. Each transmit value of the transmit parameter is associated with a different beam direction. The analysis module provides an assessment of the plurality of transmit paths of the electronic device based on the plurality of transmit values.
