Abstract:
1. A mobile terminal testing device comprising: a baseband signal output means for outputting a baseband signal having a predetermined bandwidth and signal level; a radio frequency test signal output means for converting a frequency of the baseband signal based on a predetermined oscillation frequency to generate a test signal and outputting the test signal, wherein a multicarrier test signal is generated as the test signal, the multicarrier test signal including a first radio frequency signal having a first center frequency and a second radio frequency signal having a second center frequency that is different from the first center frequency, and the multicarrier test signal is output to a mobile terminal to be tested; a reproduced baseband signal output means for reproducing the baseband signal to output a reproduced baseband signal; a frequency shift means for shifting a frequency of the reproduced baseband signal by a desired frequency shift value; and a baseband signal addition means for adding the baseband signal and the frequency-shifted reproduced baseband signal to output an added baseband signal, wherein the added baseband signal is so frequency-converted as to generate the multicarrier test signal in the radio frequency test signal output means.
