The present invention relates to a device for measuring PIM of a multi-band and a measuring method thereof. Provided is the device for measuring the PIM of the multi-band comprising a first signal generating device which generates a first frequency signal; a second signal generating device which generates a second frequency signal; a first power amp which generates an amplification first frequency signal by amplifying the first frequency signal; a second power amp which generates an amplification second frequency signal by amplifying the second frequency signal; a combiner which generates one test signal by composing the amplification first frequency signal and the amplification second frequency signal; a switching unit which generates a classified test signal by classifying the test signal according to the frequency and designates the path of the classified test signal; a multiplexer which receives the classified test signal from the switching unit, transmits the classified test signal to a measured device, filters the PIM component of the measured device according to the classified test signal, and removes the same; and a single output port which connects the multiplexer and the measured device. |
