  6. Summary • Basic Functions as well as all magnetometer relevant parameters are tested with Venus Express Magnetometer • Identical sensor • 90% identical electronics (all active parts) • Interface is tested with BB-FGE and Austrian GSE • Available at Magson • FPGA permanently under development • FGS in time • ETU’s status deviates from original plan • FGE FM’s: no showstoppers visible

  7. S/C I&T FGM Sensor configuration during S/C I&T • Level 0 - without sensor • B-field about zero if FGM in Cal Mode (preferred mode) • B-field saturated if feedback is closed • Interface full functional • Power consumption reduced by 200mW • Level 1- Sensor in Mu-metal cup • B-field about 10.000nT, Noise about 1nT • Full functionality, but B-field value not representative • Level 2 - Sensor in TCU with extended harness • B-field < 10nT, Noise <10pT/sqrt(Hz) • B-field has to be available in full quality • Delta in calibration coefficients known
