Patent number: 10838004Abstract: 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.Type: GrantFiled: August 28, 2017Date of Patent: November 17, 2020Assignee: ROHDE & SCHWARZ GMBH & CO.
