An object of the present invention is to provide a mobile terminal testing apparatus capable of improving operability. A mobile terminal testing apparatus according to the present invention is a mobile terminal testing apparatus (1) which uses one of a plurality of component carriers in carrier aggregation as a primary component carrier and the other component carriers as secondary component carriers, and makes a call connection with a mobile terminal (2) to test the carrier aggregation, the mobile terminal has a local oscillation frequency in a continuous frequency band from the primary component carrier to the secondary component carriers, and the input unit (15) collectively sets the desired parameters for the continuous frequency band.
