Note that this data rate is the maximum correlator output data rate that the SaDT links can support (given the maximum link occupancy SDP can support) and is therefore a constraint on the correlator output data rate and not the actual correlator data rate at any point in time. This data rate takes into account all Layer 1 to 7 protocol (incl SPEAD) overheads as well as all the metadata items (timestamp, IDs, counts, etc) and is therefore the maximum rate at which the correlator is allowed to produce correlator output data which includes visibilities (8 bytes per visibility), the TCI (1 byte) and the FD (1 byte) and Transient Buffer Data11SKA1-Low CBF does not currently support transfer of Transient Buffer Data. (described in section 5.4).
The total correlator output data rate is calculated as: Nchannels x Nphase bins x Nbaselines x Mbaseline / Tcorr_int + Rtransient_buffer bytes/s.
Refer to section 5.4.1.6.1 for the calculation of the Transient Buffer Data rate (Rtransient_buffer).
