Abstract: A measuring system for measuring a communications device comprising an antenna-array. The measuring system comprises a controller, a measuring device, a measuring antenna and a device mount. The measuring device performs measurements with regard to the communications device. The device mount rotates the communications device about at least one axis. The controller sets a maximum gain direction of the antenna-array. The controller (i) controls the device mount to rotate the communications device, compensating for the set maximum gain direction, until the set maximum gain direction meets a direction of the measuring antenna with respect to the communications device, and (ii) determines an actual maximum gain direction of the antenna-array by iteratively rotating the communications device and determining a respective gain for each iteration, and determines the actual maximum gain direction as a rotation of the device mount that corresponds to the iteration of maximal gain.

Abstract: The invention relates to a method and to a switching device (4) and a measurement system (1). In the method according to the invention for determining time differences between measurement signals measured by at least two couple measurement devices (2, 3), a time basis signal is first generated for the measurement devices (2, 3). A common reference signal is further generated by a signal generator (5). The common reference signal is fed to measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) via the switching device (4). A measurement signal is then fed to said measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) and the time position of the measurement signals relative to the reference signal is determined in each of the coupled measuring devices (2, 3).
