摘要

The frequency of an adjacent channel signal is reduced by a down converter ( 12 ), wherein the signal (adjacent channel signal) in a predetermined band centered around the adjacent channel frequency passes through a band-pass filter ( 22 ). At this time, a signal out of the predetermined band among the signals output from the down converter ( 12 ) by the band-pass filter ( 22 ) passes through the filter ( 22 ). An FFT section ( 32 ) outputs the signal having passed through the band-pass filter ( 22 ) by making it correspond with a frequency so that a first power measuring section ( 34 ) is used for power measurement on the basis of only the signal in a predetermined band. Therefore, power on an adjacent signal is accurately measured upon reception of a measurement signal.
