BepiColombo MPO PFM Radiated EMC tests at ESTEC 01/12/2015-09/12/2015 SERENA Instrument Summary Report

Abstract

This document provides a summary report on the testing activities named “Radiated EMC test” executed from the 1 st of December to the 9 th of December 2015 in the Rosetta clean room located at ESTEC, Noordwijk (NL), on the MPO with all payloads connected and fully operating. In particular the document describes activities and reports results of the tests performed on the SERENA FS suite as well as analyses data received from the instrument and collected by the SERENA PI-EGSE during the whole test session. Tests execution and management was mainly under the responsibility of TAS-I and ADS teams but supervised by ESA. P/L instrument teams staff was also required for verification purposes. All TM data packets, here generally analysed and discussed, were regularly stored in SERENA PI-EGSE. Moreover several screenshots and graphs showing the instrument behaviour and functionality were collected. During the Radiated EMC test SERENA worked in both emissive mode (MAXEMI) and susceptibility mode (MAXSUS). All planned tests run on the SERENA suite were performed as expected and successfully. So that the overall instrument behaviour can be considered nominal. All TM packets were received from each sub-system and for any category. Flux of HK and SCI data was regular, data quality as expected. Currents and Temperatures were nominal during the whole test session, except some little but nominal oscillations of MIPA TOF Board temperature and some random negligible spikes of ELENA Shutter temperature. All SERENA settings and thresholds were consistent to the default values. Some sets of OOL happened during the whole test session have not to be considered a concern. A remarkable event has to be mentioned: on the 8 th of December, after a reboot foreseen by the nominal procedure, STROFIO was unable to receive and execute TCs again. But power OFF of STROFIO and then power ON again allowed to recover the lost communication between STROFIO and SCU.
