Patent ID: 7148699

Claim:
A method for calibrating a second electronic device using a first electronic device, the first electronic device having a first reference characteristic and a second reference characteristic, the second electronic device having a first adjustable element and a second adjustable element, the first electronic device and the second electronic device being interconnected via one or more signal lines, the method comprising the steps of: generating a first value based at least in part upon the first reference characteristic; providing the first value to the second electronic device via one of the one or more signal lines; generating a second value, based at least in part on the first value, using the first adjustable element; comparing the second value to the first value; adjusting the first adjustable element so as to modify the second value until the second value substantially matches the first value and thus the second electronic device is calibrated using the first electronic device; generating a third value based at least in part upon the second reference characteristic; providing the third value to the second electronic device via a second one of the one or more signal lines; generating a fourth value, based at least in part upon the third value, using the second adjustable element; comparing the fourth value to the third value; and adjusting the second adjustable element so as to modify the fourth value until the fourth value substantially matches the third value.
