The invention provides a fast frequency point conversion method, which comprises the steps: an establishing frequency point of a testing instrument is a cell of a set frequency point, and a terminal carries out conformance testing of radio frequency under the set frequency point; and after the testing under the current set frequency point is finished and when frequency point conversion is determined, a deleting frequency point of the testing instrument is the cell of the current set frequency point, the establishing frequency point is the cell of a next set frequency point, and the terminal carries out the conformance testing of the radio frequency under the next set frequency point. The invention provides a device for realizing the fast frequency point conversion simultaneously, and the device and the method realize fast conversion of the frequency points in the conformance testing process of the radio frequency and reduce the consumed time of the terminal for carrying out the conformance testing of the radio frequency.
