A switching system for sequential switching of radio frequency paths is provided. The switching system comprises a plurality of inputs and a plurality of outputs, a plurality of switching elements respectively connected between the plurality of inputs and the plurality of outputs and a trigger module. In this context, multiple signal paths are defined between the plurality of inputs and the plurality of outputs corresponding to specific switch positions of the plurality of switching elements. In addition, the trigger module is adapted to generate a trigger signal in order to switch between the multiple signal paths.

Switching system and method for sequential switching of radio frequency paths

A method for performing active over-the-air measurements of a device under test with an antenna is described. The device under test with the antenna is provided. The device under test is arranged randomly in a measurement zone assigned to a measurement antenna. The phase center of the antenna of the device under test is determined. Measurement positions for the active over-the-air measurements are calculated that depend on an offset between the phase center determined and a center of the measurement zone. Further, a measurement system for over-the-air measurements is described.
