2. OVER RANGE IMPACTS APID 460/461:
• A saturated waveform in the spin plane is relatively recoverable • A saturated signal in the spin-axis is deadly. No way to tell where it really is.
SPIN FITS: • Not recoverable. We lose virtually everything if the signal goes over range.

TEST RESULTS
GENERAL NOTES
MPT Form : White background on Measured Packet Counts means <10% variance from “Expected” column. Yellow means over 10% variance.
Accelerated tests had issues with very slow packets
Telemetry Segment Packet Minimums interfered with packet counts since we could not read all the packets out of memory (some were still being worked on).
The durations of PB and WB were difficult to verify through this method. Memory capacity drives the amount collected. Estimated time is entered by the test director to check consistency between the PB and WB APIDs.
The Actual Playback time (in seconds) to empty the memory is needed for the test to get all the data out of the SSR. Normally, only half the SSR will be played out.
APID 451 Trigger Rate changed to ½ Hz (was 1 Hz) in last P345 test
APID 452 SST Engineering Data to be 1 packet/Hour (was disabled) in last P345 test
THEMIS IDPU FSW 04/18/23 20 UCB
P1 TAIL RESULTS
Measure Packet Counts match to within 10% of expectation (white background). Yellow means >10% variance.

CONCLUSION
CONCLUSIONS1. INSTRUMENT CONTROLS
Orbit Configurations are Complete and Tested All Instrument Scripts Tested Script Collections #0002 thru #0004 are Flight Ready
2. TELEMETRY STORAGE Survey Collection and Storage Operating per Specification Burst Collection of 92 MB Understood.
3. COMPRESSION Processor Compresses in much less than 4 hours Even While Spin-Fitting Compression Ratios Between 2.1 and 2.6
4. TELEMETRY PLAYBACK Playback Sequence Tested All Engineering and Survey Data is played out Full Burst Playback Pushes Downlink past 375 Mb Allocation (30 min downlink) Required Burst Playback (<17 MB) plays “best” 2-3 Bursts out of 8
5. SPACECRAFT MEMORY APID 405 (FGM 8 Hz) for 2 Hours/Orbit will Generate 0.439 MB Needs to be accounted on the BAU memory ledger.
