Agenda

General Updates

• BOF Files
  • Jason has started to look over notes from Aridnam and will use these when working on new designs
  • Randy is working on c1500x4096 mode needed for BL; still floor planning and trying to eliminate timing errors
  • lbw spectral lines modes will be used as the basis for 100 MHz pulsar modes going forward
  • We will look into having Vereese help with floor planning
  • Ryan needs to update BOF file status webpage with results from latest tests
• Wideband AP
  • Randy estimates 2 - 3 hours left on board design
  • Vereese is interested in writing control code once we are ready for that stage
• Software
  • Justin and Ryan looked into IF Manager crashes
    • With help from Joe we think we traced to this to unexpected ID numbering of new VEGAS Manager parameters in DLL's
  • Just added support for power samplers, so these are now working well
  • Still seeing problem with observer mode being passed from Coordinator to Managers
    • Seems to happen when switching observing mode without loading a new BOF file
    • Justin believes that he has the problem narrowed down and is working on a fix
  • Need to add functionality for VEGAS to act as switching signal master in pulsar modes
    • Loading a new BOF file seems to whipe out switching signal engine
    • Jason or Randy will double check BOF files to make sure switching signal control blocks are present
  • Ryan has written config tool MR, and Justin has started revewing
