FTP Fringe Test
Selected results from the JIVE SFXC software correlator
4 March 2024
Mode:
3.6 cm, 4096 Mbps, 32 BBC channels, 32 MHz filters, 2-bit sampling.
Participating antennas:
Westerbork (Wb), Effelsberg (Ef), Medicina (Mc), Noto (Nt), Onsala 20m (O6), Tianma 65m (T6),
Urumqi (Ur), Torun (Tr), Yebes 40m (Ys), Hartebeesthoek (Hh), Irbene 32m (Ir), Kunming (Km).
With 2 s integration times on J0854+2006.
Notes:
-- Km successful 4 Gbps test (Mk6 and VDIF setup).
-- Mc/T6/Km bottom of IF loses sensitivity (expected due to the various fixed LOs). In general, band edges at 4 Gbps stations have stranger shapes.
-- Tr polarization inputs were swapped (was corrected in vex).
-- Fringes to everyone. No unexpected issues.
