The invention discloses a device and method for improving vector frequency conversion transmission parameter measurement efficiency, and belongs to the technical field of measurement. The device comprises a non-same-frequency amplitude calibration module and a non-same-frequency phase calibration module. According to the amplitude calibration and phase calibration integrated implementation method under the non-same-frequency condition, the measurement steps of phase calibration can be greatly simplified, and the testing efficiency of the vector frequency converter is improved; according to the invention, non-same-frequency amplitude calibration and phase calibration can be completed at the same time without changing the jumper connection state of the front panel of the IF receiving end, and the problems of connection error introduction and measurement precision influence caused by repeated plugging and unplugging of the jumper are eliminated; the phase calibration steps are greatly reduced, the calculated amo
