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. |
