Paper Abstract

We describe a low-cost personal computer-based generator designed to produce timing signals needed for the operation of visible or infrared focal plane devices and other electronic systems requiring a large number of complex parallel timing control signals with precise relative phase relationships. The implementation is a high-speed static memory digital board which can be programmed by copying the timing waveforms emanating from a commercial generator (e.g. Pulse Instruments PI-5800A, Interface Technology RS-690, etc.). This simple approach retains most of the desirable features associated with using a commercial timing generator such as flexibility and the use of user-friendly software for timing synthesis. The approach permits the implementation of timing generation to multiple focal plane devices, each operated by a unique local copying and replicating timing board, from timing data synthesized on a central commercial timing generator. As evidenced in our laboratory, this approach has resulted in a lower cost for operating multiple focal plane devices with little loss of flexibility and programmability.
