VEGAS observation preparation Status:

  1. half part of the IF band has poor SNR. why? is it fixed already? how to fix?
    • DONE Resolved and ready for test
  2. the start up problem:
    • DONE Resolved and ready for test
  3. 16 bins of the spectra have poor SNR. (an FPGA design problem).
    • DONE Resolved and ready for test
  4. valon locking problem.
    • DONE Solved by a power cycle - inconsistent status between python GUI and laptop
  5. what else needs to get fixed before we observe?
    • DONE 12 second gaps
      • Resolved and ready for test
  6. what tests should we do before we have enough confidence to start observing?
    • Test Pulsar
      • Ready to go - test 22-Jan PM
        • version with 'broken-up' observation data to later verify the ability to stitch together multiple observations
      • Broadband noise test 23 Jan AM
    • Known Pulsar - with gap to prove obs can be combined
      • Scheduled GBT time 23-Jan PM
      • On-Off continuum obs for sensitivity
    • Six hour data collection test period would be nice - can be done with test pulsar
