Abstract: The invention is a device and a method for transmitting data between two physical interfaces which in motion in relation to one another along a trajectory. The device has a data transmission unit disposed between the physical interfaces, and a local oscillator is assigned to the physical interfaces to inject a local system time prevailing at the location of one of the physical interfaces. The local oscillator has at least one of the physical interfaces for receiving and generating at least one clock signal which is transmitted to the data transmitter and the local oscillator at least at the other physical interface. The other physical interface has a receiver for the at least one clock signal transmittable via the data transmission unit and a synchronizer of the local system times based on the received clock signal; and a buffer memory.

Abstract: An arrangement for calibrating a vector network analyzer (VNA) is substantially secure against operating errors and offers cost-effective calibration by connecting calibration components. Each calibration component includes a transponder and a non-volatile memory which contains, as non-changeable data, at least the type of the component and an individual identification number and, as changeable data, at least the number of calibration processes performed with this calibration component. The VNA includes a wireless interface for reading at least the non-changeable data of a respective calibration component and for incrementing the stored number of the calibration processes performed with this calibration component.
