Abstract:
1. A mobile communication terminal test device that includes a signal generation device in which a plurality of sub-carriers are arranged in a frequency domain, transmits the signal generated by the signal generation device as a test signal to a mobile communication terminal, receives a response signal to the test signal from the mobile communication terminal, and tests the mobile communication terminal, comprising: sub-carrier generation means for generating the plurality of sub-carriers based on a predetermined modulation system from input data; time domain conversion means for receiving the generated plurality of sub-carriers and converting the plurality of sub-carriers into a signal in a time domain; frequency characteristic storage means for storing data of frequency characteristics for at least one of amplitude-frequency characteristics and phase-frequency characteristics of each of the sub-carriers in advance; frequency characteristic calculation means for adding the frequency characteristics to each of the sub-carriers generated by the sub-carrier generation means in a predetermined time unit based on the data of the frequency characteristics and outputting the addition result; test data output means for outputting test data, which is a source of the test signal, as the input data to the sub-carrier generation means; up-conversion means for converting the signal in the time domain into a predetermined radio-frequency test signal and outputting the predetermined radio-frequency test signal to the mobile communication terminal; down-conversion means for receiving a response signal to the test signal from the mobile communication terminal and converting the received signal into a response signal with a predetermined frequency; response signal demodulation means for demodulating the response signal output from the down-conversion means; and analysis means for analyzing the demodulated response signal, wherein the time domain conversion means receives the plurality of sub-carriers output from the frequency characteristic calculation means and converts the sub-carriers into the signal in the time domain.
