Tidbinbilla notes for V185b
Config notes
- Centre freq = 2280 MHz
- Polarisation = RCP (IF1), LCP (IF2)
- 1st LO = 2000 MHz
- mix to 160 MHz into DAS
- so 2nd LO for USB mix = 2280 - 2000 + 160 = 440 MHz
- DAS profile = ti16s_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

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 ~ +291 ms
- * models for encoder and position should be 3SPIG.AC1 and 3SCIB.SEM respectively
- ap band s
- ap move r=240
- ap semn 3spig.ac1
- ap semn 3scib.sem
- ap radec 217.08656 -42.13415 (1424-418)
- ap mode ac1
- 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 S band and [apply])
- if fails, try SC 99
- make carrier 2280 MHz
- if fail to pick up correct LNA:
- D1 set uwv reset
- d1 set uwv srla2o2
- D2 D CNF 4
- (select S band and [apply])
- if fails, try SC 99
- 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
- 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
