Abstract
A measuring device for the interface of a transmission link with full-duplex transmission in two-wire common band operation includes a device for simulating the interface that allows the signal in the near-to-far direction on the transmission link to be separated from the return signal. To precisely perform jitter measurements on the interface of the transmission link during ongoing transmission using a conventional jitter measuring instrument, the measuring device has a differentiator followed by a comparator connected between a subtractor and the jitter measuring instrument.
