1. An operation method of an electronic device which communicates with an external device including a transmission equalizer through a first channel, the method comprising:
measuring figure of merit (FoM) values for a first group of presets having different preset types, based on equalized signals output from the transmission equalizer adjusted based on the first group of presets;
identifying a preset type of a first preset corresponding to a first FoM value which is a greatest value from among the FoM values for the first group of presets;
measuring FoM values for a second group of presets having the identified preset type, based on equalized signals output from the transmission equalizer adjusted based on the second group of presets;
determining a second preset corresponding to a second FoM value which is a greatest value from among the first FoM value and the FoM values for the second group of presets; and
transmitting an equalizing setup request that controls the transmission equalizer to the external device, based on the determined second preset.
