PROBLEM TO BE SOLVED: To realize frequency conversion stably with high accuracy by flexibly tracking a secular change and an environment condition without causing a configuration to become greatly complicated or costs to increase in a frequency conversion support device for correcting a deviation in the frequency of a local oscillation signal which is the cause of the disturbance of a frequency spectrum occurring in the result of frequency conversion.SOLUTION: The frequency conversion support device comprises: power acquisition means for obtaining power included in a second signal generated by the frequency conversion of a first signal and being distributed in a band including the frequency of a carrier of the second signal on a frequency axis; and frequency offset compensation means for updating the frequency of the local oscillation signal presented to the frequency conversion in a direction in which disparity in the distribution of the power on the frequency axis decreases. |
