THEMIS INSTRUMENT CDR Peer Review SYSTEM-1 UCB, April 19, 2004

TITLE: Test Flow RFA CODE: UCB-10

REQUESTED BY: Preble SPECIFIC REQUEST:

We recommend that UCB define the development, engineering model, qualification, and acceptance testing approach for all of the THEMIS instruments. We think that this could be contained in an I&T test plan. For starters, however, we recommend that each instrument team (or the project-level system engineering team) develop a flow chart identifying the testing that will be conducted. The conditions of the testing such as temperature, vacuum or air, cycles, etc. should be added when available.

Response: THM_SYS_005d_Instrument Payload Verification Plan and Environmental Test Specification provides the test plan for all instruments. Flow charts for each instrument are contained in the plan. The THEMIS Environmental Test Matrix contains specific test conditions such as vacuum or air, number of cycles, etc.

FGM Level 0 – Without Sensor (Aliveness)• 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 about 200mW

FGM Level 1 – Sensor in Mu-metal cap (Limited Performance Test)• B-field about 10,000nT, Noise about 1nT

• Full functionality,

but B-field not representative

FGM Level 2 – Sensor in TCU (Comprehensive Performance Test) • B-field < 10nT, Noise <10pT/sqrt (Hz)

• B-field has to be available in full quality

• Delta in calibration coefficients known
