The upgrade leverages off the development of an eight-channel data acquisition system featuring modern FPGA flexibility that was designed for the monopulse BPM system. This upgrade also provides an external clock signal synchronized to the APS revolution clock that will eliminate the aliasing caused by the Bergoz asynchronous multiplexing interacting with different accelerator fill patterns. The upgrade will revitalize this system and demonstrate a cost-effective approach to improved beam stability, reliability, and enhanced postmortem capabilities. In this paper we will discuss the upgrade system specifications, design, and prototype test results.
