D. R. BettFONT Meeting 5 th May New DAQ scheme Addresses several issues: 1.Rob’s DAQ modified to cope with two bunch mode known not to correctly perform interleaving of feedback, latency scans 2.Necessary to maintain a separate instance of code for each board – to add new features, each must be modified 3.Code distributed and difficult to manage

D. R. BettFONT Meeting 5 th May Improved VIs FONT5_board.vi –General improvement to legibility –Live monitoring of DACs –Direct referencing of control registers Mover_control.vi –Parallel execution enabled Scope_daq.vi –Single sample mode added

D. R. BettFONT Meeting 5 th May Brand New VIs Main.vi –Monitor board data –Synchronize data logging, interleaving Scan.vi –Automated variation of parameters EPICS.vi –effectively “spun out” from FONT5_board.vi Hardware_assignment.vi

D. R. BettFONT Meeting 5 th May Main.vi Save logic (synchronized) Interleave feedback Position monitoring Phase monitoring Sum and difference monitoring (saturation) Skew monitoring (timing)

D. R. BettFONT Meeting 5 th May scan.vi Set scan attributes Scan results (phasing LOs)

D. R. BettFONT Meeting 5 th May scan.vi Scan results (zeroing movers)

D. R. BettFONT Meeting 5 th May Summary No functionality lost FONT5 board VI –more generic –less monolithic All hardware code collected together Facility for automatic parameter scans Some bugs to iron out

D. R. BettFONT Meeting 5 th May Appendix: Other VIs Define the hardware layout to be stored in the.set file Knowledge of which phase shifter controls which channel required for automatic phasing of LOs

D. R. BettFONT Meeting 5 th May Appendix: Other VIs EPICS logic stripped out of the FONT5 board VI Presented graphically and made available for logging
