ACTIVITY TITLE: Load and Dump STIS Onboard Memory

ID: STIS-02

APPLICABLE SMOV REQUIREMENTS: L.10.4.5.1.4

DESCRIPTION: This activity will repeat the Operate state portion of the activity implemented during SMOV-2 for proposal 7058.

This activity is a test and verification of the STIS dump of CS (Control Section) memory capability. Areas to dump include: EEPROM, PROM, EDAC RAM, and Buffer RAM with the CS in OPERATE mode. With the MAMA Interface Electronics (MIE) and CS both in OPERATE, perform a full dump of the CS EEPROM, PROM, and EDAC RAM. Then copy MIE data from MIE RAM and MIE PROM to CS Buffer RAM. Finally, dump the portion of the CS Buffer RAM containing the data as normal science images.

IMPLEMENTATION METHOD: Stored commanding

DEPENDENCIES: Successful recovery of STIS from safe mode following SM4.

DURATION: 20 minutes

DATA REQUIREMENTS: 35 Mbits

ANALYSES & EXPECTED RESULTS: The memory dumps will be checked for proper format, and the large images will be compared against images stared in the memory manager.

COMMENTS: Proposal 11347, PI Alan Welty.
