It was the first aperture synthesis radio telescope to use phased array feed technology, enabling the formation of up to nine dual-polarisation beams. A series of astronomical observations were made with BETA to test the operation of the phased array feeds, and to help the commissioning and operation of the final ASKAP telescope.

The first prototype phased-array feeds (PAF) proved the concept worked, but their performance was not optimum. In 2013–2014, while the BETA array was operational, significant sections of ASKAP were redesigned to improve performance in a process known as the ASKAP design enhancement (ADE). The main

Although the ADE delayed the completion of ASKAP, this was felt to be justified as the resulting system had better performance, was lower cost, and more reliable. The first ADE PAF was installed in August 2014. By April 2016, nine ADE PAFs were installed, together with the new ADE correlator, and
