    Description

      • Use the TPM data flowing into LOW CBF (either existing 1-station data, or 4 substation-data) to create an end-to-end signal chain
        • 1-station is existing functionality, if 4-station not available then use the CNIC virtual digitiser mode that can generate any number of substations
      • Use the timestamps in the SPS SPEAD packets in the calculation of the correlator visibility output packet timestamps
      • process the RF data in the correlator to show real data flowing through the signal processing stages
      • develop firmware and software to enable the correlator to start processing at any arbitrary time, not just start processing on a canned sequence starting at a given time
