Agenda

General Updates From the Past Week

Priorities For Next Two Weeks

Reminder: Ryan is on vacation until December 13
  • Switching signal calculation
    • New bof files and manager are able to drive the cal signal but the actual swper is still substantially different from requested swper
    • TODO: Correct calculation of actual swper and test with Astrid in either simulator or during maintenance time
  • Scan ending early with newest c1500x0512
    • PKTIDX still wrapping in status screen
    • TODO: Modify guppi_daq and/or dibas_status to properly track PKTIDX so we can look for odd behavior
  • Bandpass issues in i0800x0064, 0128, 8192
    • Tone shows up in the correct bins, but generates spurs if injected at Fs/8 or nearby
      • Spurs move with the test tone and decrease with amplitude if you move away from Fs/8
      • May be problem with MMCM or OGP calibration
    • TODO: Justin to discuss MMCM and OGP calibration with Paul M
