Session Notes for Research and Development session: rd1402 Prepared by C. Thomas, NVI, Inc./GSFC =========================================================== PURPOSE AND GENERAL NOTES The purpose of rd1402 is to test 512 Mbps recording mode at the anticipated mode for CONT14. This frequency setup uses 2-bit sampling with no fanout and 32 tracks. The schedule was generated using SNRs of 20 at X-band and 15 at S-band for all stations. All stations have been fully scheduled. The schedule uses a selection of 60 sources from the good geodetic source list. The minimum subnet size was set to 2. ============================================================================= ----- Parameter listing -------------------------------------- Experiment: RD1402 Description CONT14 CHECKOUT Scheduler: NASA Correlator: HAYS Start: 2014-085-18:00:00 End: 2014-086-18:00:00 Current yyyyddd: 2014085 (2014.23) ( 16743 MJD, WED. 26MAR.)
