A method for determining a channel quality for the transmission of data in the channel by a test device. The test device transmits the data with the determined channel quality to a device to be tested which determines one or more pieces of decision information. The device to be tested forwards the piece(s) of decision information to the test device as a response signal and the test device reads the piece(s) of decision information from the response signal. The piece(s) of decision information from the response signal is/are uniquely attributed to a transmission mode to be adjusted. The initially determined channel quality is also uniquely attributed to an expected transmission mode. The expected transmission mode is compared with the transmission mode to be adjusted in a comparative unit in the evaluation unit, thereby allowing a statement regarding the correctness of the transmission mode to be adjusted.

Method for testing the transmission modes of a radio device

A device and method for determining and displaying on a display element the status of at least one synchronization implemented in an electronic measuring instrument or a telecommunications device is provided. The device includes several functional units provided within the electronic measuring instrument or the telecommunications device, and each functional unit determines at least one parameter, the value of which corresponds to the status of the synchronization implemented in the respective functional unit.
