Downlink signals output from a transmission and reception unit are combined with an interference signal of a CW, a resultant signal is applied to a mobile terminal, throughputs for respective interference signal frequencies for the downlink signals are collectively measured, a signal suppression band of the filter is fitted to a frequency band of the downlink signal determined not to reach a defined value, and re-measurement and re-determination of the throughput for the downlink signal among the collectively measured throughputs are performed. In a case where throughputs collectively measured at a certain interference signal frequency are equal to or greater than the defined value and a case where re-measured throughputs of all the downlink signals are equal to or greater than the defined value, the interference signal frequency is switched to the next interference signal frequency, and collective throughput measurement is performed.
