      Development of tools that support the use of PST deployment in a wider integration test have been completed. The software developed include:

      • CBF simulator that can generate a synthetic data stream with an injected sinusoidal tone in a specified frequency channel.
      • Complete deployment of PST AA0.5 voltage recorder which can receive a CBF data stream and write the data files to the local file system for long term storage.
      • Simple analysis software which can process the recorded data streams, unpack and denormalise the recorded data, integrate the signal into a bandpass and report the channel and frequency with the maximum power.

      The PST "end-to-end" tests that reside in the ska-pst-integration repository have been extended from a single happy-path test to Integration Tests that cover:

      • aborting a scan if no packets have been received from CBF.
      • a scan where invalid packets have been received from CBF.

      A reduction in Technical Debt was undertaken to ensure all C++ log messages conform to the SKAO logging standards.

    Description

      To support integration and testing of the signal chain at the Low PSI, the PST Team will

      • develop CI System Tests that span the system tests identified in the LOW Integration Test Plan using a simple CBF simulator,
      • work with Perentie to develop manual (and possibly automated) tests that verify the interface between CBF and PST and the integrity of the signal chain.

      Various other improvements to PST will be implemented, including:

      • reporting additional statistics about discarded, malformed and mis-ordered packets
      • updating the UDP packet generator to optionally introduce packet transmission errors 
      • generating log messages in the required format
      • correctly reporting configuration errors; and
      • correctly reporting CBF/PST interface errors
