Abstract: A passive intermodulation (PIM) measurement device for measuring a PIM in at least one of installation equipments and a distribution network within a distributed antenna system (DAS), the PIM measurement device included in a relay unit of the DAS the PIM measurement device includes a pulse generation unit a PIM detection unit and a controller. The pulse generation unit generates a two-tone pulse signal having frequencies different from each other. The PIM detection unit detects intermodulation (IM) signals fed back from the installation equipments or the distribution network in the DAS corresponding to the propagation of the two-tone pulse signal. The controller detects PIM generation information in the DAS based on the fed-back IM signal.
