Claim:
1. A monitoring device for a distributed antenna system including at least two node units communicatively coupled to each other and transmitting input base station signals to user terminals or transmitting an input user terminal signal to at least one base station through the node units, the monitoring device comprising: a controller configured to generate a data dump command for a first target signal passing through a first signal path in a digital part of at least one target node unit among the node units in response to a dump request input; and an interface unit configured to transmit the data dump command to the target node unit through a network and receive response data from the target node unit through the network, wherein the controller is further configured to generate first quality information indicative of quality of the first target signal by using the response data, and wherein the target node unit is configured to, in response to the data dump command, store first data corresponding to the first target signal being processed by signal processing components related to the first signal path and transmit the first data to the monitoring device as the response data through the network.
