Instrument models and test campaigns

Overview of tests and test campaigns:CQM-ILT, CQM-IMT , FM 1, and FM 2

SVR 20 – 21 April 2006, Groningen

introduction
Introduction
  • DM-ILT program finished (band 1, 5, partial warm units)
  • Validation of test equipment & EGSE “finished”
  • Testing as much as possible via CUS scripts, configuration files, MIB
  • Analysis of results partly via database/IA
cqm eqm ilt
CQM (EQM)-ILT
  • Early October 2004 – 12 December 2004
  • Configuration:
    • FP Band 3 (H/V)
    • WBS one polarization
    • HRS one polarization
    • ICU no redundancy (AVM)
    • OBS … - 2.22
    • LO (band 3A/B, few frequencies); LSU simulator
  • Goal: Preparation for IMT (no external stimulator)
  • Tests: Functional test (no tuning); stability (; standing waves)
  • Conclusions on ripples, diplexer behavior (together with 2 side bands and standing waves), calibration source, noise temperature, LO reproducibility, chopper & OBS (non-)behavior
  • Start of understanding HIFI
cqm imt
CQM-IMT
  • At ‘satellite’ level
    • In old ISO cryostat, with PACS and SPIRE
    • Control via CCS, Herschel PDU simulator
    • With LSU simulator
    • ICU CFM 2 for EMC test
  • October (IMT), November/December 2005(EMC, thermal behavior)
  • Results: see presentation of Nick Whyborn
  • Also results regarding integration procedures, use of IEGSE, etc
slide7
FM 1
  • FM1 refers to FPU tests with MSA’s 1, 2, 3, 5
  • November/December 2005
  • To test FPU performance (presentation of P. Dieleman)
  • To measure the beams (presentation of M. Jochemsen)
  • Feedback (new grids in band 1, polarization correction in band 5, chopper magnets): implemented
  • In this period also the start of the WBS integration with ICU/EGSE/HCSS
    • inrush current reduction, OBSW debugging, new HCSS release, new OBSW version, temperature stability of environment, … : not yet finished completely

---------------------

  • After FM1: completion of the FPU and modifications
slide8
FM 2
  • Now going on
  • FPU performance of all bands and beam measurements
    • Check improvements
  • Continuation of WBS integration
    • ICU (AVM2, OBS 3.5), GSE and tested with scripts: KOSMA performance not fully reproduced
  • Start of ICU - HRS integration
    • HRS integrated with ICU, WBS (AVM2, OBS 3.5), GSE and tested with scripts: CESR performance reproduced (TBC)
  • Test equipment is being upgraded (// set up, re-imager controlled by scripts, etc.)
  • Next: Integration with ICU ..; preparation for cold vibration
