THEMIS Instrument CDR 6 UCB, April 19-20, 2004 SPB Assembly and Test Plan

THEMIS Instrument CDR 7 UCB, April 19-20, 2004 SPB Assembly and Test Plan

THEMIS Instrument CDR 8 UCB, April 19-20, 2004 SPB Assembly and Test Plan

THEMIS Instrument CDR 9 UCB, April 19-20, 2004 Instrument (Suite) I&T Plan Integration and Test Instrument I&T takes place at UCBSSL. Environmental (TVAC, Vibe, Suite EMC as per THM-SYS- 005 Environmental Verification Spec). Limited and Comprehensive Performance Testing: –SPB Motor Simulators (aka. Motor-in-a-Box) and AXB Test FrangiBolts (aka. FrangiBolt-in-a-Box) used for pre- and post- environmental functional tests of deploy mechanisms, as well as dummy electrical loads during “fake” TVAC deploy testing. –Internal DC and AC functional test capability used for pre- and post-environmental functional tests of sensors; sensors may be directly stimulated via ACTEST line on Test/Enable plug. End-to-End SPB and AXB TVAC Deploy Testing (IDPU- controlled; using SPB Takeup Reels, AXB Horiz. Deploy Track in EFI Snout). Phase intercalibration between EFI, SCM, and FGM performed using EFI Test/Enable Plugs, SCM Mu-Metal Box, FGM TCU and 12-channel, 16-bit, +/- 10-V National Instruments DAC system.

THEMIS Instrument CDR 10 UCB, April 19-20, 2004 S/C (Probe) I&T Plan Integration and Test Probe I&T takes place at Swales Aerospace. Environmental (TVAC, Vibe, Shock, EMI; as per THM-SYS- 005 Environmental Verification Spec). Limited and Comprehensive Performance Testing: –Sensors via internal DC and AC Functional Test capability, monitored through ITOS. –Actuators via external Boom Loads Simulator (BLS) and Test/Enable plugs, monitored through ITOS. –Sensors may be stimulated externally via breakout on BLS, if required (non-standard test). Red/Green tag items: –One red tag Snout Cover per SPB (4 total). –One red/green Test/Enable plug per SPB (4 total). –One red tag Tube Cover per AXB (2 total). –One red/green Test/Enable plug supporting both AXBs (1 total)
