Initial ground-based system tests have been run on the first full-size, second generation (Mk II) ASKAP phased array feed receiver at the Murchison Radio-astronomy Observatory in Western Australia.
Now on site, ground aperture array tests on the full-size Mk II prototype will provide vital information about the system operation.
The installation of the prototype PAF on the ground near an ASKAP antenna went smoothly as did the installation of its digital backend at the MRO Control Building. This system successfully captured 188 radio signals, each of 600 MHz bandwidth, from the PAF and transported them over 1.4 km of optical fibre to the digital backend.
With initial tests complete, the team will now analyse the results to generate an assessment of system performance before returning to the MRO to prepare for installation of the PAF on to an ASKAP antenna.
