MOBILE TERMINAL TEST DEVICE AND TEST METHOD

PROBLEM TO BE SOLVED: To rightly perform power measurement of a mobile terminal that is adaptive to a dual carrier system.SOLUTION: A message for outputting a signal of a first carrier is sent out, a reception signal is monitored while setting a state where the signal of the first carrier outputted from the mobile terminal can be received, and power after the lapse of a predetermined time from the timing in which a shift amount of power of the reception signal exceeds a trigger level, is detected as power of the signal of the first carrier. Next, a message for reducing transmission power is sent out such that a leakage component included in a signal band of a second carrier, in a signal component of the first carrier, ranges not to exceed the trigger level, and after transmission power is reduced, a message for outputting a signal of the second carrier is sent out. A reception signal is monitored while setting a state where the signal of the second carrier can be received, and power after the lapse of a predetermined time from the timing in which a shift amount of the power of the reception signal exceeds the trigger level, is detected as power of the signal of the second carrier.SELECTED DRAWING: Figure 1 【課題】デュアルキャリア方式に対応した移動体端末のパワー測定を正しく行なう。【解決手段】第１キャリアの信号を出力させるためのメッセージを送出し、移動体端末から出力される第１キャリアの信号を受信できる状態に設定して受信信号を監視し、受信信号のパワーの変移量がトリガレベルを越えたタイミングから所定時間経過後のパワーを第１キャリアの信号のパワーとして検出する。次に、第１キャリアの信号成分のうち、第２キャリアの信号帯域に含まれる漏れ成分のパワーがトリガレベルを越えない範囲となるように送信電力を低下させるためのメッセージを送出し、送信電力低下後に、第２キャリアの信号を出力させるためのメッセージを送出し、第２キャリアの信号を受信できる状態に設定して受信信号を監視し、受信信号のパワーの変移量がトリガレベルを越えたタイミングから所定時間経過後のパワーを第２キャリアの信号のパワーとして検出する。【選択図】図１
