Abstract: A test system and method of performing a run-time measurement for calibration of a device used for time-of-flight measurement are disclosed. The method comprises: providing a measurement device, a device under test and a directive component having three ports; connecting the directive component to a transmission port of the measurement device and a reception port of the measurement device; generating a signal by a signal generator; forwarding the signal to the directive component; receiving at least a response by a signal receiver; and determining a loop time indicative of the run-time between the directive component and the device under test as well as a time of internal processing of the device under test, wherein the loop time is independent of a signal processing time of a signal path between the measurement device and the directive component.

Abstract: 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.

Abstract: A measuring device for providing an angle of departure determining test signal to a device under test, is provided. The measuring device comprises a signal generator and a single output port. The signal generator is adapted to generate the angle of departure determining test signal, emulating an antenna array angle of departure determining signal, comprised of a plurality of individual array antenna signals, thereby emulating an angle of departure of the angle of departure determining test signal. The single output port is adapted to output the angle of departure determining test signal to the device under test.
