Abstract
An apparatus and method for calibrating a first sampling circuit with a second sampling circuit having a similar impulse response. The second sampling circuit includes a sample and hold circuit that provides an output indicative of the potential at the sampling circuit input of the second sampling circuit at a time determined by a signal at the trigger pulse input of the second sampling circuit. The apparatus includes a trigger pulse generating circuit for generating a sequence of trigger pulse pairs, each pair having a first pulse that is delayed relative to a second pulse. Each pulse is applied to a corresponding trigger input of the sampling circuits. The first sampling circuit is assumed to generate a kick-out pulse indicative of its impulse response when triggered by the first pulse. A controller measures the output of the second sampling circuit for each delay.
