Issue Date: | 2009 | Number: | PL-LFI-PST-RP-069 | Abstract: | In this report, we show the results of the DAE calibration activity performed during the CPV test phase of the Planck/LFI instrument. The activity has the purpose of finding the best gain and offset values for the 44 ACA implemented in the LFI, and characterizing the so-called “offset problem”, i.e. a spurious offset that the DAE applies to scientific data under some conditions. During the CPV phase, the DAE calibration has been repeated twice, because after the first calibration a new configuration for the LFI ACA biases has been loaded and the absolute voltage levels fed to the DAE have changed consequently. This document shows the results for both calibrations. | Note: | Planck LFI Commissioning and Performance Verification (CPV) | URI: | http://hdl.handle.net/20.500.12386/33262 | Fulltext: | open |
