Device and method for investigating a cable system

Abstract

Devices (10) support a use of investigation signals for investigating cable systems comprising cables (101) and loads (111). The loads (111) comprise rectifier circuits (201) coupled to storage circuits (202). The devices (10) comprise charger circuits (1) for producing charging signals for charging the storage circuits (202) such that they have reduced impacts on performances of the investigation signals. The devices (10) may further comprise discharger circuits (2) for discharging signaling circuits (121) after being charged by the charger circuits (1). The devices (10) may further comprise investigation circuits (3) for producing the investigation signals and controller circuits (4) for controlling the other circuits (1-3) and reception circuits (5) for receiving responses to the investigation signals and analysis circuits (6) for analyzing the responses in view of the investigation signals and for in response to analysis results defining a problem (102-104) and/or a location of a problem (102-104).
