The data for v189a should be recorded to the first of the new sets of xraids (7 x 500 GB)\ \ Data being recorded to first set of Xraid disks as labeled: /data/xraid0. Interestingly this is the right-hand bank of disks.\ \ Data recorded as follows:\ \ 09:50:00 → 09:50:30 - duration was set to 30s, whoops!\ 09:58:00 → 10:27:12 Stopped to reconfigure caching settings on the Xraids\ 10:28:00 → end\ \ Notes:\ 09:50:00 On point and recording\ 12:28:00 (approx time) IF2 unplugged briefly for a sanity check\ 12:37:00 Antenna off point for ~ 30s for another sanity check\ 12:42:00 After conversation with Adam, can see no problems with the \
system so suspect lack of fringes to Tid is due to checking \
software not handling the mixture of bands and pols correctly. \
Have double checked frequency setup, antenna pointing, recorder\
clock etc and all looks correct.\

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\

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\
