Abstract
A frequency variation provider gives a predetermined frequency variation when a situation in which a mobile terminal approaches or is separated from a base station is simulated to a downlink (DL) signal which is transmitted to a mobile terminal by a transmitting unit. A receiving unit receives an uplink (UL) signal output from the mobile terminal which has received the DL signal and converts the UL signal into a baseband signal. A frequency variation detector detects a frequency variation of the UL signal from the baseband signal. A frequency corrector corrects the frequency of a local signal which is used by the receiving unit to obtain the baseband signal, on the basis of the detected frequency variation. A variation characteristic display displays the characteristics of the frequency variation of the UL signal transmitted from the mobile terminal on a display unit.
