Description

In this contribution, we present the development of general purpose 8-channel 5 GSample/s waveform recorder and 10 GSample/s function generator for a 3rd generation AMD Radio Frequency System-On-Chip (RFSoC). The system has an EPICS IOC running on a CPU inside the RFSoC, as well as a direct fiber optic interface to the Swiss Light Source event system. This enables to trigger the data acquisition and waveform synthesis via accelerator events, to synchronize the system with beam injection, pinger magnets, etc. Applications include the monitoring of the attenuated return signals of the SLS multibunch feedback (MBFB) kicker magnets, with the goal to automatically tune the MBFB round-trip delay by temporally overlapping the signal of a single electron bunch and the MBFB kicker response to this bunch. Lab and beam test results will be presented, as well as the benefits of upgrading the present SLS MBFB hardware based on RFSoC generation 1 to generation 3.
