|Description||18 cm disk-based pulsar astrometry|
|DAS 1 Skyfreq||1650.00|
|DAS 2 Skyfreq||1682.00|
|DAS Mode||vsop.pro (telescope)|
This is a disk based experiment. Do NOT delete the data after recording!!!!
Record on /data/removable or /data/xraid as appropriate. Telescope disk allocations are covered under the telescope specific notes linked to below.
TIDBINBILLA AND HOBART FREQUENCIES AND POLARISATIONS
Tid only has LCP at 1.6 GHz and should set up to record 4 channels of LCP at 256 Mbps using the vsop profile on the DAS, matched to the 4 channel frequencies given in the table. This will allow Tid to match LCP at all 4 frequencies for the ATNF antennas.
Likewise, Hobart should also set up to record LCP at 256 Mbps using the vsop DAS profile. Like Tid this will allow LCP coverage of all 4 frequencies of the ATNF antennas, and will exactly match Tidbinbilla. This setup will require splitting the RF signal and setting up two IF chains, one into each IFP of the DAS.
|IFP#1 Skyfreq||1650.00 LCP|
|IFP#2 Skyfreq||1682.00 LCP|
DAS & Recorder Setup
Hobart and Tidbinbilla connect DAS directly to VSIC as per normal
Parkes, ATCA & Mopra connect both DAS to single VSIC input using 'Huygens' cable. DAS#2 should be configured to be the higher frequency and connected to input#2 (input with clock lines connected).
