The embodiment of the invention discloses a sending calibration method and control equipment. A calibration method includes transmitting first data comprising calibration data and a first checksum to a storage device according to each training parameter set, recording a plurality of error indicators respectively which are corresponding to the multiple training parameter sets and from the storage device, and identifying one of multiple training parameter sets as a predetermined parameter set according to the plurality of error indicators respectively corresponding to the multiple training parameter sets, wherein each error indicator indicates whether transmitting of the first data according to the corresponding training parameter set is successful. Sending calibration time can be saved according to the embodiment.
