The Planck Low Frequency Instrument (LFI) radiometers have been tested extensively during several dedicated campaigns. The present paper reports the principal noise properties of the LFI radiometers. A brief description of the LFI radiometers is given along with details of the test campaigns relevant to determination of noise properties. Current estimates of flight sensitivities, 1/ f parameters, and noise effective bandwidths are presented. The LFI receivers exhibit exceptional 1/ f noise, and their white noise performance is sufficient for the science goals of Planck.

Abstract
The Planck Low Frequency Instrument (LFI) radiometers have been tested extensively during several dedicated campaigns. The present paper reports the principal noise properties of the LFI radiometers. A brief description of the LFI radiometers is given along with details of the test campaigns relevant to determination of noise properties. Current estimates of flight sensitivities, 1/ f parameters, and noise effective bandwidths are presented. The LFI receivers exhibit exceptional 1/ f noise, and their white noise performance is sufficient for the science goals of Planck.File in questo prodotto:
