Abstract: Embodiments of a device and method to automatically acquire signal quality metrics in a digital communication system are disclosed. The device may include acquisition means to sample the likelihood of a digital communication signal passing through a grid of time and amplitude regions, and storage means by which such likelihood measurements may be accumulated in a computer memory array for analysis. A state machine may execute a method that controls both the acquisition means and the storage means, requiring minimal intervention from supervisory systems.

Abstract: An example embodiment includes an optoelectronic module.
