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.

Claim (Index 1):
A passive intermodulation (PIM) measurement device included in a unit of a distributed antenna system (DAS), the PIM measurement device comprising:\n a memory to store instructions; and a processor, coupled to the memory, to facilitate execution of the instructions to perform operations, comprising:\n generating a coded signal including two-tone pulse having frequencies different from each other; \n measuring a first time when the coded signal is generated or propagated to at least one of installation equipment and a distribution network; \n measuring a second time when an intermodulation (IM) signal is detected, wherein the IM signal is fed back from the at least one of installation equipment and the distribution network, corresponding to the propagation of the coded signal; \n calculating a distance corresponding to a time difference between the first time and the second time; \n determining a PIM location based on the calculated distance; and \n generating PIM information associated with the PIM location based on the determined PIM location.
