Abstract: A time synchronized measurement system has a master device and a slave device. The master device and the slave device each have a time measurement device for assigning a corresponding time of sending and/or receiving a piece of measurement information. The master device also has a reference clock pulse-generating device for transmitting a reference clock signal to the slave device. The reference clock signal is modulated by a piece of information on a common time basis for the master device and the slave device.

Abstract: A protocol test device has at least two channels which each have a transmit and a receive side, the protocol test device being designed to switch a signal transmitted from a first channel to the receive side of a second channel. A method for determining, by approximation, a transmit time of a data package in the protocol test device includes the following steps: a) transmitting a signal via the transmit side of the first channel, b) forwarding the signal to the receive side of the second channel, and, c) in the receive side of the second channel allocating a time stamp to the signal.

Abstract: A method for calibrating an adjustable frequency generator having a voltage-controlled oscillator which is preceded by a computer via a digital-to-analog converter. The control input of the oscillator is coupled to a calibrating device comprising a series circuit comprising a digital phase detector and a lowpass filter forming a phase-locked loop circuit arrangement. By the computer, a digital-to-analog converter is caused, upon a frequency reference value signal, to deliver a control voltage to the oscillator which corresponds to the output voltage of the lowpass filter prior to the start of the calibrating process. A digital value corresponding to the control voltage is stored in the computer together with a digital reference value corresponding to the given frequency.
