Tidbinbilla notes for V188a
Config notes
- Centre freq = 2285 MHz
- Polarisation = RCP→IFP1, LCP-IFP2
- 1st LO = 2000 MHz
- mix to 160 MHz into DAS
- so 2nd LO for USB mix = 2285 - 2000 + 160 = 445 MHz
- DAS profile = vsop_f.pro
- receiver configs:
- DCC1: RCP → LNA2 (low noise path) → out (output 1 for SNT monitoring). So `SRLA2O1
- DCC2: LCP → LNA1 (high noise diplexed path) → out (output 2 for SNT monitoring). So 'SLDA1O2
SOE
Before the track
- Tapes
- get labels
- load first set

- LCP → IF2
- 2nd LOs 1 and 2 to 445 MHz
- PCFS
- sched files
- fix timing
- add source commands
- modify PRC file
- ND control
- copy calon, caloff, toload, tosky from v185bti (edit for correct NMC)
- VFC patching
- patch in S-band and set LOs to 272 MHz
- S2 config
- start DAS software
- configuration ti16s_f.pro
- adjust attenuators
- tidvsi
- 203.5.58.205 (admin LAN only, use jplvisitor account)
- check time
- vsib_record -m 3 -c xxxx -e /dev/vsib -t 32400s -o /data/removable/v188a/v188a-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

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
- check atten levels
