      abstract     = {Controlling stored beams in particle accelerators requires
                      specially designed RF signals, such as needed for spill
                      control via transverse excitation. The software-defined
                      radio (SDR) technology is adopted as a low cost, yet highly
                      flexible setup to generate such signals in the kHz to MHz
                      regime. A feedback system is build using a combination of
                      digital signal processing with GNU Radio and RF
                      Network-on-Chip (RFNoC) on a Universal Software Radio
                      Peripheral (USRP). The system enables digitization of
                      signals from particle detectors and direct tuning of the
                      produced RF waveforms via a feedback controller –
                      implemented on a single device. To allow for triggered
                      operation and to reduce the loop delay to a few ms, custom
                      OOT and RFNoC blocks have been implemented. This
                      contribution reports on the implementation and first test
                      results with beam of the developed spill control system.},
