The Digital Line Analyser EDCT 20 is a hand-held, battery operated, multi-function measuring instrument for in or out-of-service bit error and signal measurements. EDCT 20 can work in both unframed and framed modes for end-to-end and loopback testing of digital channels. It offers features such as: timeslot monitoring; timeslot access; set-ups and result storages. With the installation of the optional data communication unit, EDCT 20 is able to verify the interfaces (V.24, V.35 and V.11) between the DTE (Data Terminal Equipment) and the DCE (Data Communication Equipment), both in synchronous and asynchronous systems. Results can be stored in it's non-volatile memory or logged on PC via USB.
