摘要： A method of measuring a total radiated power of a device under test by a test system with a base station simulator, a measurement antenna assigned to the base station simulator and a control and/or measurement equipment is described. The method includes: establishing a radio resource control connection between the device under test and the base station simulator via the measurement antenna; activating an uplink-beam lock function at the device under test; and performing a total radiated power measurement by the control and/or measurement equipment while continuously sending a downlink signal from the base station simulator via the measurement antenna to the device under test. A test system is further described.

摘要： A measurement system for testing a device under test is described that comprises at least one signal unit for processing a signal, at least two measurement antennas, at least two reflectors, a shielded space, and a testing position for the device under test. Each measurement antenna is orientated with respect to the testing position such that the testing position is located in at least one of a side lobe area and a back lobe area of the measurement antennas. The reflectors are located such that each reflector generates and/or collimates a planar wave at different angles with respect to the testing position. Further, a method for performing test measurements is described.

摘要： A measurement system is described, comprising a signal processing equipment, an antenna unit, a device under test, and a resonant cavity surrounding the antenna unit and the device under test. The signal processing equipment is at least one of a signal generation equipment and a signal measurement equipment. The resonant cavity has a resonance for a frequency corresponding to at least one of the frequency used for testing the device under test and its multiples. The device under test is located within the resonant cavity such that a standing wave is established inside the resonant cavity during testing the device under test. The standing wave has an electric field distribution with maxima and minima. The antenna unit is located within the resonant cavity such that the antenna unit is assigned to a maximum of the electric field. Further, a method for testing a device under test is described.

摘要： Test arrangement and method for wirelessly testing a device under test. An in-band test signal and a further interference signal are emitted to the device under test by a test arrangement comprising a single antenna. For this purpose, a linear polarized in-band test signal and a linear polarized interference signal are generated. The in-band test signal and the interference signal are combined by a transducer to a circular polarized signal and the circular polarized signal comprising the in-band test signal and interference signal is used for testing the device under test.

摘要： A testing method for testing mobile communication devices comprises measuring a three-dimensional antenna pattern of an active phased antenna array (AAS) of the mobile communication device, with the AAS being maintained at a specific beamforming alignment during the measurement. A predefined base fading profile is calibrated with the measured three-dimensional antenna pattern to obtain an optimized fading profile adapted to the specific beamforming alignment. A channel model for emulation of a base station is emulated on the basis of the optimized fading profile. The method further involves performing a receiver test on the mobile communication device using the emulated channel model. The testing method may in some embodiments be a radiated two-stage over-the-air (RTS-OTA) testing method.

摘要： Measurement arrangement and measurement method for measuring spurious emissions of a wireless device. The measurement arrangement comprises at least two antennas, wherein a first antenna is arranged at proximity of the wireless device. In a first step, frequencies relating to spurious emissions are determined by measuring wireless signals received by the first antenna. In a second step, the spurious emissions are measured by the second device.
