Abstract
The frequency of an adjacent channel signal is reduced by a down converter (), wherein the signal (adjacent channel signal) in a predetermined band centered around the adjacent channel frequency passes through a band-pass filter (). At this time, a signal out of the predetermined band among the signals output from the down converter () by the band-pass filter () passes through the filter (). An FFT section () outputs the signal having passed through the band-pass filter () by making it correspond with a frequency so that a first power measuring section () 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.
