Abstract:
A remote apparatus includes: a plurality of sub amplification units amplifying radio frequency (RF) signals of different frequency bands, respectively; a test signal generation unit generating test signals of a frequency band for any one sub amplification unit among the plurality of sub amplification units; a conversion unit converting intermodulation (IM) signals generated in response to the test signals into a plurality of conversion IM signals by using a conversion signal of which a frequency is swept; and a control unit determining a degree of an intermodulation distortion by the any one sub amplification unit based on signal levels of the plurality of the conversion IM signals.
