Abstract: We describe recent developments in measuring both signal and noise in phased array feeds for radio astronomy at CSIRO. We introduce new techniques including aperture array noise measurements with beamforming weights matched to a reflector's focal field. Weights are calculated via antenna-range and in-reflector measurements. We also describe the separation of system temperature and aperture efficiency via drift scans.<br />Comment: 5 pages, 7 figures, accepted for publication in Antennas and Propagation (EuCAP), 2016 10th European Conference on (updated abstract)
