T 09248

Ceduna-Hobart diagnostic VLBI

4816 MHz sky freq

Ceduna used Agilent & Wiltron for first LO (at 9 dBm), replacing fixed oscillator. SMY01 and SML were used as second LOs at 436 MHz for Ch1 and Ch2 respectively. DAS profile VSOP_HO.PRO

Ceduna used Agilent instead of fixed 4.1 GHz oscillator between ~17:40 and 18:20:40

Wiltron used as first LO between 18:21:50 and 18:52:10

Ceduna recorded to Fermi disks 17 & 18

Hobart data on external eSATA Fermi disks. Fermi 7 & 8.

1. vex2config.pl -cross -evlbi -new t09248.skd
2. Edited input file for fringe check - 300sec integration fixed start time, telescope delays, ports
3. vex2model_updated.pl t09248.skd
4. machines and threads file are the same as t09246
5. edited run.sh to point to this exp
6. Ran run.sh, note trying this without swapped pols… I think (again) that we were fine from here on
7. No fringes, input file was wrong. only had 1 frequency specified… try again!
8. Betterer but apparently we STILL had/have? crossed pols. edit input file to match t09240
