TGBT15A_915_62 - continued balance testing

See CICADAGreenBankSpectrometer2016Sep07


Details:
  • 11:00am - Justin switches to new version. Start again at mode 10
  • 11:25am CheckMode10 Scan 16
  • Bank A took too long to be ready. Repeat, scan 17
  • All of IF Rack 1,2,5,7 cannot balance because signal is too weak. Yet no error message from Astrid
  • IF levels are around 0.5V, when the target is 3V. Attenuators are at 0dB (i.e. minimum). This should be a warning message!
  • CheckMode11, Scan 18 - same issue with IF rack. Also Mode 12.
  • Mode 12, Scan 19 - aborts due to invalid data
  • Get Amber to TaskMaster restart everything
  • Mode 12 again, Scan 20
  • VEGAS aborts again - give up at this point!
  • Nothing obvious Ray can do, so stop testing and wait for Joe to return
  • Justin switches back
  • Scan 21 - aborts because Antenna is back in system
  • Scan 22 - mode 12 - data looks fine.
  • noon - finito
