A system for vector network analysis of a device under test, comprising at least two measurement receivers, at least one signal generator device formed separately from the at least two measurement receivers, and at least one data processing unit connected with the measurement receivers. The connection between the data processing unit and at least one of the measurement receivers is flexible so that the position of the measurement receiver is adjustable. Further, a method for vector network analysis of a device under test is described.

System for vector network analysis of a device under test as well as method for vector network analysis of a device under test

Summarizing, the present invention relates to a test arrangement in the test method for acquiring test data in the surrounding of a device under test. At least two measurement devices are arranged in the surrounding of the device under test, wherein the two measurement devices are communicatively coupled for phase locking. At least one of the measurement devices can be moved around the device under test for acquiring measurement data, wherein the measurement devices comprise a measurement antenna and the vectorial measurement receiver. Accordingly, during the measurements, the at least one vectorial measurement receiver is moved around together with the measurement antenna, wherein the spatial relationship between the measurement antenna and the vectorial measurement receiver is remained constant during the movement.
