Zusammenfassung: | PROBLEM TO BE SOLVED: To enable transmission power to be adjusted without relying on an external measuring instrument.SOLUTION: A power measuring unit (10) for measuring an input signal from a signal source (radio unit tester 18) or measuring power of a transmission signal is provided in a self-device. The input signal from the signal source and the transmission power are switched by switches (a change-over switch 16, a front-end switch 28) to perform an input to the power measuring unit. Then, a control unit (CPU 42) adjusts the transmission power on the basis of a signal level of the input signal measured by the power measuring unit and a signal level of the transmission power.
【課題】外部の計測器に依存することなく、送信電力を調整可能にする。【解決手段】信号源(無線機テスタ18)からの入力信号を測定し、または送信信号の電力を測定する電力測定部(10)を自機内に備える。前記信号源からの入力信号と前記送信電力とをスイッチ(切替スイッチ16、フロントエンドスイッチ28)により切り替えて前記電力測定部に入力する。そして、制御部(CPU42)では、前記電力測定部で測定された入力信号の信号レベルと前記送信電力の信号レベルとに基づいて前記送信電力を調整する。【選択図】図1 |
