Device for analysing the transmission quality of digital radio links

摘要

A device is described for analysing the transmission quality of digital radio links. A digital input (1, 2) is provided via which a counter (3) can be actuated to add up transmission errors. A computing unit (4) with a permanently stored operating system is coupled with the counter (3) which it can read and reset. Memory means (5) are provided for temporary storage of values which are provided by the computing unit (4). The stored values are output via an output (6, 7). A flip flop (11), which is connected to the computing unit (4) for reading and resetting, can be set via a further digital input (10). The flip flop (11) is set when the link breaks down. When the flip flop (11) is set, the computing unit (4) sets a permanently pre-defined value rather than the transmission errors added up in the counter (3).
