Abstract: Disclosed herein are an apparatus and method for measuring a broadband Passive Intermodulation Distortion (PIMD) signal. The apparatus for measuring a broadband PIMD signal includes a Radio Frequency (RF) processing unit for combining one or more transmission signals into a single output signal and transmitting the output signal to a feeder so as to measure a PIMD signal and for generating a beat frequency signal using the PIMD signal received from the feeder, and a digital processing unit for transferring a control signal required so as to control the RF processing unit, receiving the beat frequency signal, and then measuring a location of a passive element in the feeder in which the PIMD signal has been generated by performing digital signal processing on the beat frequency signal.
