One embodiment of the present invention relates to a digital phase locked loop configured to generate a plurality of time-aligned output clock signals having different frequency values. Ar1, Ar2, and Ar3 together form a tridentate ligand coordinated to the platinum through atoms X, Y, and Z, respectively, and X, Y, and Z are independently carbon or nitrogen. A mask may then be applied to the resulting electronic assembly. During an operating mode of the digital communications link and during otherwise normal system operation, the service processor switches a selected one of the plurality of lanes from the operating mode to a test mode, performs an eye scan of the selected lane, stores data corresponding to the eye scan of the selected lane, and returns the selected lane to the operating mode. The mission module is removable, and may be one of several mission modules available to the cart.
