    摘要: An antenna coupler for testing a mobile-radio device with a coupling element formed in a flat manner by strip conductors on a printed-circuit board and with a retaining device formed on a first side of the printed-circuit board for positioning a mobile-radio device in the vicinity of the coupling element. On the first side of the printed-circuit board, at least one slit structure is introduced into an ground metallization formed there. For feeding the slit structure serving as the coupling element, at least one stripline formed on the second side facing away from it forms a microstripline with the ground metallization remaining between the slit structure of the first side.

    摘要: A method and a measuring device for synchronizing measuring channel assemblies are provided. A reference signal is produced by a reference signal source. The reference signal is supplied to the individual measuring channel assemblies of the measuring device. A clock signal generator is used to produce a clock signal at a low frequency, the clock signal generator being connected to each measuring channel assembly by a respective connecting line of the same length. The clock signal is supplied through a phase corrector element for the purpose of correcting the phase of the reference signal in each measuring channel assembly to the phase of the clock signal.

    摘要: A switch-extender is connected to a measurement system and to several DUTs. It splits a signal from the measurement system into several signals so that the several DUTs receive the same signal and can therefore be tested in parallel. The switch-extender further includes at least one amplifier and/or at least one attenuator for every output port so that every signal has the same signal level no matter what the individual attenuation factor of the signal connectors or of the internal printed circuit board is. Furthermore a method for calibrating the measurement system as well as for the switch-extender and the signal connectors describes how to obtain the needed calibration values both for the downlink path and for the uplink path without changing the signal connector.
