    • 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.
    • 用于检测耦合到电缆系统的电缆(6)的负载(2,3)中或附近的装置(1)包括分析部件(11),用于分析用于馈送负载的电缆信号的波形(11) 2,3)和决定部分(12),用于响应于分析结果决定负载(2,3)中是否存在问题。 负载(2,3)可以经由驱动器(4,5)耦合到电缆(6)。 负载(2,3)中或其附近的问题可能导致驱动器(4,5)修正波形波峰值或波谷波谷附近的值。 分析结果可以定义波形是否已被修改超过阈值。 在波峰或波谷附近修正波形的值可以包括加到波峰上的正脉冲或添加到波谷的负脉冲。
