Abstract
A device (1) for detecting a problem in or near a load (2, 3) coupled to a cable (6) of a cable system comprises an analyzing part (11) for analyzing a waveform of a cable signal for feeding the load (2, 3) and a deciding part (12) for in response to an analysis result deciding whether a problem in or near the load (2, 3) is present or not. The load (2, 3) may be coupled to the cable (6) via a driver (4, 5). The problem in or near the load (2, 3) may result in the driver (4, 5) amending a value of the waveform at or near a crest or a trough of the waveform. The analysis result may define whether the waveform has been amended by more than a threshold or not. The amending of the value of the waveform at or near the crest or the trough may comprise a positive pulse added to a crest or a negative pulse added to a trough.
