    Abstract

    Several performance parameters of the Planck 70 GHz radiometers were measured during the test campaign, the main ones being system noise temperature (Tsys), radiometric bandwidth (ƒÒ), and 1/f noise knee frequency (fk). The requirements for these parameters were met in some, but not in all of the constructed receivers. The best achieved values were Tsys = 27 K, ƒÒ = 12 GHz and fk = 43 mHz. Many other parameters were also determined, such as isolation between the reference and sky channels, sensitivity to operating temperature and bias fluctuations, etc. In addition to the performance tests, the receivers (like any spacecraft equipment) were subjected to rigorous environmental tests including EMC, thermal vacuum testing (TVT) and mechanical vibration. Some of these tests were performed outside the main test facility.
