This is an old revision of the document!


The data for v189a should be recorded to the first of the new sets of xraids (7 x 500 GB)\ \ Data being recorded to first set of Xraid disks as labeled: /data/xraid0. Interestingly this is the right-hand bank of disks.\ \ Data recorded as follows:\ \ 09:50:00 → 09:50:30 - duration was set to 30s, whoops!\ 09:58:00 → 10:27:12 Stopped to reconfigure caching settings on the Xraids\ 10:28:00 → end\ \ Notes:\ 09:50:00 On point and recording\ 12:28:00 (approx time) IF2 unplugged briefly for a sanity check\ 12:37:00 Antenna off point for ~ 30s for another sanity check\ 12:42:00 After conversation with Adam, can see no problems with the \

          system so suspect lack of fringes to Tid is due to checking \
          software not handling the mixture of bands and pols correctly. \
          Have double checked frequency setup, antenna pointing, recorder\
          clock etc and all looks correct.\

Tidbinbilla Setup notes for V189a\

\

Config notes\

  • Centre freqs = 1650, 1682 MHz MHz\
  • Polarisation = LCP\
  • 1st LO = 1380 MHz\
  • mix to 160 MHz into DAS\
  • so 2nd LO for USB mix \
    • IFP1: 1650 - 1380 + 160 = 430 MHz\
    • IFP1: 1682 - 1380 + 160 = 462 MHz\
  • DAS profile = vsop_f.pro\
