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)



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



SOE\\

Before the track\\

  • Block 0 rack config
    • Split L-band signal then amplify, attennuate, mix etc to IFP1, 2
    • 2nd LOs
      • 1: 430 MHz
      • 2: 462 MHz
  • PCFS
    • sched files
      • fix timing
      • add source commands
    • modify PRC file
      • VFC patching
        • patch in L-band and set LOs to 286 MHz (1666 MHz Sky)
      • S2 config
  • start DAS software
    • configuration vsop_f.pro
    • adjust attenuators
  • tidvsi
    • 203.5.58.205 (admin LAN only, use jplvisitor account)
    • check time
    • use disko
    • vsib_record -m 3 -c xxxx -e /dev/vsib -t 32400s -o /blah/v189a-ti
      • configure and start
  • xplot
    • on pcfs40: /usr2/st/vlbisrv/start_vlbisrv dflt
    • on eac40: /opt/rmc/bin/xplot -rh pcfs40
  • start PCFS software
    • ssh ops@pcfs40
    • pcfsa-remote
      • S2, S-RCP, S-LCP, maintenance
    • start the schedule
    • configure VFCs with ifds and vclba

At start of track\\

  • NMC
    • Link
      • Build link with antenna and receiver, spacecraft 50 (VLBI), pass 0, two receivers.
    • antenna startup
      • in NMC:CTRL Connection Control:
        • AP D TRK (to show the track display)
          • Check for:
          • * delut ~ +229 ms
          • * models for encoder and position should be 3SPIG.AC1 and 3SCIB.SEM respectively
        • ap band s
        • ap move r=240
        • ap semn 3spig.ac2
        • ap semn 3scib.sem
        • ap radec 9.63649 -24.94850 (j0038-24)
        • ap mode ac2
        • ap d sts (check all green. click on antenna to see brakes status)
        • ap trk (start the antenna)
        • (make safety page)
        • ap resm trk
    • start three connection blocks
      • connection blocks → NDcontrol (Note PID)
      • connection blocks → UWVcontrol (Note PID)
      • connection blocks → APCcontrol (Note PID)
    • start the E-log TDN
      • TDNs → log?
      • move to 'logs' workspace
    • receiver config
      • us d smap
      • us d xmap
      • (double-click on dichroic to move it IN)
      • (configure with double-clicks)
      • D1 D CNF 3
      • (select SC 99 and S band and [apply])
      • make carrier 2280 MHz
      • if fail to pick up correct LNA:
        • D1 set uwv reset
        • d1 set uwv srla2o2
      • D2 D CNF 4
      • (select SC 99 and S band and [apply])
      • make carrier 2280 MHz
      • if fail to pick up correct LNA:
        • select connection “none”
        • select connection DSS43SO2
      • if still failing
        • D1 set uwv reset
        • d1 set uwv srla2o2
      • configure noise diode
        • d1 d prf 3 and d2 d prf 4
        • click on REC button in CNF windows
        • select 12.5K and frequency = on, apply
        • then enable/disable, check in each IF
        • to modulate
        • * 0.25 K, 20 Hz, 5s, enable
        • repeat for D2


  • boresight
    • manual offsets e.g:
      • ap po xel 0.1
  • PCFS
