The Array Controller is a complete acquisition system for use with the NEP 256 channel photo conductive readout integrated circuit. The on board microcontroller provides all signals needed to operate the array. Operation and calibration of the per pixel dark current skimmers is handled by the DLL and the array microcontroller. Physically the Controller is designed to attach to a standard 28 pin tub package (pictured in right column). The dual board system separates the acquisition function (upper board) from the TE cooler controller (lower board).
