    "abstract": "The PEP-II B Factory Low-Level RF System (LLRF) is a fully programmable VXI\nbased design running under an EPICS control environment. Several RF feedback\nloops are used to control longitudinal coupled-bunch modes driven by the\naccelerating mode of the RF cavities. This paper updates the performance of the\nLLRF system as beam currents reach design levels. Modifications which enhance\nthe stability, diagnostics, and overall operational performance are described.\nRecent data from high current operation is included.",
