Antenna Startup\\


The antenna pointing files, subreflector rotation etc are different depending on the observation. Below is an example.\ \

  • 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
        • 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 → 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 and DAS
    • check atten levels
