 +
 +===== Comments: =====
 +
 +This is a fringe-check for v190f. ​ The schedule is incorporated into the v190f schedule so there is no need to 
 +change schedules in between the fringe check and the observation.
 +
 +Record onto /​data/​removable/​ for 59 minutes - don't forget to start the real recording for v190f!!!
 +
 +**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).
