| 摘要 |
The invention relates to a measuring device (29) for the interface (2) of a transmission link (1) with full duplex transmission in a two-wire common frequency operation, in which a device (8) emulates the interface (2) enabling the outgoing signal (Uhin) on the transmission to be separated from the return signal (Urück). In order to carry out precise jitter measurements on the interface (2) of the transmission link (1) during transmission mode using an ordinary jitter measuring device (26), the inventive measuring device (29) includes a derivative unit (19) with a downstream comparator (25) connected to a subtractor (15), wherein the comparator (25) is connected to the jitter measuring device (26) on the output side. |
