A fixture and a measurement system are provided. The fixture is adapted for electrically connecting a measurement device with a device under test, DUT, in particular a wireless DUT, and for mechanically holding the DUT. The fixture comprises a clamp for clamping the DUT; a male plug for engaging a mating socket of the DUT; and an electrical cable connected to the plug on one end and connectable with the measurement device at its other end. The fixture is arranged to mechanically hold the DUT such that the DUT can be rotated relative to the measurement device. The fixture reduces a shielding effect in respect of antenna modules of the DUT.

Fixture for a device under test

A mobile radio testing device for protocol testing of a device under test is provided. The mobile radio testing device comprises a downlink path and an uplink path, wherein the uplink path comprises at least a first analysis mode and a second analysis mode. In this context, the mobile radio testing device includes a demodulation processing unit for analyzing signals from the device under test in the first analysis mode. In addition, the second analysis mode analyzes signals from the device under test without using the demodulation processing unit.

Mobile radio testing device and method for protocol testing

A test apparatus for testing a base station of a wireless communication system, comprises a downlink port, which receives a downlink signal from the base station, an uplink port, which emits an uplink signal to the base station, a signal processing unit, which is coupled to the downlink port and analyzes the downlink signal for timing information and generates a timing synchronization signal based on the downlink signal, and a signal generator, which is coupled to the signal processing unit and the uplink port and generates a predetermined signal frame and emits the generated predetermined signal frame based on the synchronization signal via the uplink port to the base station.
