1. A method for calibrating a receiver of an isolator product, the method comprising adjusting a peaking frequency of a receiver signal path of a first integrated circuit die of the isolator product and a gain of the receiver signal path based on a predetermined peaking frequency, a predetermined gain, a first level of a diagnostic signal during a first interval, and a second level of the diagnostic signal during a second interval, the first interval and the second interval being non-overlapping intervals.
