PROBLEM TO BE SOLVED: To obtain a multi-path generator with a function generating a quantitative multi-path environment in a test-use transmitter/receiver placed in a radio base station. SOLUTION: A test-use transmitter/receiver 16 is provided with a transmission section 10 that generates a transmission source signal not in a multi-path state and outputs it according to an instruction, a multi-path generator 12 that receives the source signal from the transmission section 10 and that adds a phase and a noise component of the source signal to the signal according to the instruction and transmits the result, and a control section 14 that instructs the transmission section 10 on an output of the source signal and that instructs the generator 12 on change of the phase of the source signal and addition of the noise component so as to control each section. |
