Abstract: A test station may include a test host, testing devices, and a test enclosure. A device under test (DUT) having a near-field communications (NFC) antenna may be placed in the test enclosure during production testing. The testing devices may have test antennas that may convey NFC test signals to the DUT in the test enclosure. Distances between test antennas and the DUT may be monitored by measuring path loss from the test antennas throughout testing. The testing station may also include a test unit and an RF test antenna. The test unit may use the RF test antenna to convey RF test signals to the DUT in the test enclosure. The DUT is marked as a passing DUT if gathered test data is satisfactory for each testing device in the test station and distance measurements between the test antennas and the DUT throughout testing are consistent with calibration measurements.

Abstract: Radio frequency test systems for characterizing antenna performance in various radio coexistence scenarios are provided. In one suitable arrangement, a test system may be used to perform passive radio coexistence characterization. During passive radio coexistence characterization, at least one signal generator may be used to feed aggressor signals directly to antennas within an electronic device under test (DUT). The aggressor signals may generate undesired interference signals in a victim frequency band, which can then be received and analyzed using a spectrum analyzer. During active radio coexistence characterization, at least one radio communications emulator may be used to communicate with a DUT via a first test antenna. While the DUT is communicating with the at least one radio communications emulator, test signals may also be conveyed between DUT 10 and a second test antenna. Test signals conveyed through the second test antenna may be used in obtaining signal interference level measurements.
