Experiment Summary - Hobart
| Experiment | Rx | Agilent | Pol. | DAS profile | Second LO(s) | Coherence Tone | Nota bene |
| v255j | 6.7 (5) | 12.2 GHz | RCP, LCP | VSOP.PRO | 468 & 810 MHz 810 & 810 MHz | 788.125 830.875 | Two frequency setups. Changes can be automated in the snap file. |
| v389a | 1.4 (2) | 4.15 GHz | RCP, LCP | VSOP_HO.PRO | 802 MHz | 694.5 | See http://www-ra.phys.utas.edu.au/wiki/index.php?n=MtPleasant26m.Lbandcircular for instructions on getting Circular polarisation |
| v255k | 6.7 (5) | 12.2 GHz | RCP, LCP | VSOP.PRO | 468 & 810 MHz 810 & 810 MHz | 788.125 830.875 | Two frequency setups. Changes can be automated in the snap file. |
| v252s | 8.4 (6) | 14 GHz | RCP only (RF switches at XOXX on the Folly Interface ) | VSOP.PRO | 777 & 809 | 841.4 & 844.6 | |
| v271f | S/X (1) | N/A | RCP only | N/A | N/A | Test using the vertex radiator - should appear as steady sine wave on CRO above the DAS PC 821.601 MHz for vc01 USB 824.801 MHz for vc02 USB 828.001 MHz for vc03 USB 832.801 MHz for vc04 USB 836.001 MHz for vc05 USB 844.001 MHz for vc06 USB 847.201 MHz for vc07 USB 850.401 MHz for vc08 USB | The experiment only uses vc01-08. |
| vx016b | 8.4 (5) | 14 GHz | RCP,LCP | 64MHZ_N.PRO | 793 MHz | 843.0 | Needs BG3 cable (currently installed) |
Note that the frequency for the coherence tone refers to the output of the CH 1 band splitter beneath the frequency translator (rack 6). A tone at the given frequency should return a 5 MHz coherence signal from the CH 1 band splitter.
SMY01 should be used for the channel 1 LO of the frequency translator and the SML for channel 2. The upper SMX is used for the tone.
Experiment Summary - Ceduna
| Experiment | Rx | Agilent | Pol. | DAS profile | Second LO(s) | Coherence Tone | Nota bene |
| v255j | 6.7 | 11.1 GHz | RCP, LCP | VSOP.PRO | 468 & 810 MHz 810 & 810 MHz | 788.125 830.875 | Two frequency setups. Changes can be automated in the snap file. |
| v255k | 6.7 | 11.1 GHz | RCP, LCP | VSOP.PRO | 468 & 810 MHz 810 & 810 MHz | 788.125 830.875 | Two frequency setups. Changes can be automated in the snap file. |
| v252s | 8.4 | 13.04 GHz | RCP only | VSOP.PRO | 637 & 669 | 841.4 & 844.6 | |
| v271f | 8.4 | 13.04 GHz | RCP only | VSOPX0Y0.PRO(?) | 428 & 684 MHz | 820.5 | Change the frequencies through rs.tcl - SMY01 should be 428 and SMY02 should be 684. VSOP profile needs checking. |
| vx016b | 8.4 | 13.04 GHz | RCP,LCP | 64MHZ_F.PRO | 653 MHz | 843.0 | Needs BG3 cable (currently installed) |
Note that the frequency for the coherence tone refers to the output of the CH 1 band splitter beneath the frequency translator (rack 6). A tone at the given frequency should return a 5 MHz coherence signal from the CH 1 band splitter.
For the v271f & v252s experiments, we need to be able to change these remotely. If we use SMY01 and SMY02 then Bev doesn't need to make an extra trip out to the station. This does mean that we won't be able to check coherence though.
