Abstract
This document is divided in two parts. In the first part we present an overview of the algorithms used by the REBA to compress the voltage output of the Planck/LFI radiometer. We also sum up the results of the REBA calibration and verification activity done during the Planck Integrate Satellite tests in Liége. We present them in terms of the sigma/q parameter, in order to allow for a better comparison with other similar requirements from HFI. We also explain the advantages of not using sigma/q as a measurement of the quantization error. In the second part of the document, we discuss which are the expected differences between the calibration of CSL data and the calibration that is going to be done in flight. It is expected that a number of effects not considered during the CSL tests will require a more careful tuning of the compressor, in order to take into account the sky signal and the impact of total-power quantization noise on the data analysis.
