VLBI Observing Using the DBBC Amp Mark 5 C
You must first power up the DBBC, Mark5C and Glapper using the Internet power switch (ipscd.phys.utas.edu.au).
After booting, log in first to the DBBC with
Set up the IFs, frequencies and bandwidths as per usual and run pps_sync
Check the clkoff reading of the DBBC with the FS command
Run fila10g_double.bat [in C:\DBBC\bin\] to set up the Fila10G with appropriate network settings, etc. To communicate with the Fila10G, use PuTTY. Check that the time is correct - you may have to set it manually as the default procedure is usually out by a few [integer] seconds. This can be fixed at the correlator but it’s far better to fix it at the beginning. To see the current time, use

If recording to Mark5B, remember to set the clock rate to 64 MHz with
