The FPGA-based continuous FFT tune measurement system for the LHC and its test at the CERN SPS
2007
2007 IEEE Particle Accelerator Conference (PAC)
A base band tune (BBQ) measurement system has recently been developed at CERN based on a highsensitivity direct-diode detection technique followed by a high resolution FFT algorithm implemented in an FPGA. The FPGA based digital processing allows the acquisition of continuous real-time spectra with 32-bit resolution, while a digital frequency synthesiser (DFS) can provide acquisition synchronised chirp excitation. All the implemented algorithms support dynamic reconfiguration of processing and
