Patent ID: 7133956

Claim:
An electronic device with a serial ATA interface, comprising: a signal output device outputting a serial data signal to a serial ATA bus which connects the electronic device to another electronic device, said another electronic device including another serial ATA interface; a cable length designation device for designating a cable length of the serial ATA bus in accordance with a user operation; an amplitude parameter generation device for generating, in accordance with the cable length designated by the cable length designation device, an amplitude parameter for determining an amplitude of the serial data signal when the signal output device outputs the serial data signal, the amplitude determined by the amplitude parameter enabling the amplitude of the serial data signal to fall within a range, stipulated in serial ATA interface standards, when said another electronic device receives the serial data signal; and a signal amplitude adjusting device for adjusting the serial data signal to the amplitude determined by the amplitude parameter, when the signal output device outputs the serial data signal.
