The first results from ground-based system tests on the full-size second generation (Mk II) phased array feed receiver have indicated impressive system temperature across the ASKAP band.
These preliminary results are very encouraging and indicate that the Mk II PAF performs much better than the first generation PAFs already deployed on the first six ASKAP antennas at the MRO, which are currently being used for commissioning activities.
The ground-based tests are invaluable to help the team understand how the Mk II PAF functions in the radio-quiet environment of the MRO.
