Provided is an electronic device includes an interface for connection to an external device; and a processor electrically connected to the interface, wherein the at least one processor is configured to: set a first radio frequency (RF) signal port of a first chipset to operate in RF signal transmission mode, and set a second RF signal port of a second chipset to operate in RF signal reception mode; obtain an error of transmission performance of the first RF signal port based on a comparison between a designated transmission reference that is input to the first RF signal port and a characteristic of a first intermediate frequency (IF) signal that is output via the second RF signal port; obtain a first compensation value to enable the transmission performance of the first RF signal port to converge to the transmission reference, on the basis of the error of the transmission performance; and store at least one of the error of the transmission performance and the first compensation value in the first chipset via the interface.
