CUTTAIA, FRANCESCOFRANCESCOCUTTAIASTRINGHETTI, LUCALUCASTRINGHETTI2024-03-192024-03-192009http://hdl.handle.net/20.500.12386/34980This Note shows the strategy to proposed to tune the LFI LNA’s (Vg1 & Vg2) in the test campaign at Satellite Level to be performed in CSL (Centre Spatiale de Liege) during the next Summer 2008 . The baseline option was accepted to be the MATRIX scheme , mixing together Vg1 and Vg2 values. The main limit to this method is given ( in CSL ) by the time required to explore a large range of parameters, since in CSL it is limited and strictly related with the 4K cooler cooldown profile. This note wants to give an overview of the philosophy and possible advantages or limits related with one or another strategy.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
