7. SCE Mini-Emulator Provides Instrument Data Interfaces only
GSEOS Interface is fully compliant
Non-flight use only

8. SCE Full-Emulator
Provides Instrument Data, Power and Temperature Interfaces
GSEOS Interface is fully compliant
Designed for use with Flight hardware

9. SPP SC Emulator Updates
Update Requirements to SPP Instrument ICDs and SpW ICD for WISPR DPU
Provide A/B UART interfaces (SCE control of active port; inactive port will be monitored only)
Provide SpW link with configurable SpW bus schedule
Support Virtual PPS (no distinct 1PPS line)
Support 400 KBAUD Telemetry link from FIELDS and SWEAP
GSEOS version 7 will be used for SPP
Mini- and Full-Emulators will have gated-PPS test output with GSEOS command for enable/disable/one-shot with programmable pulse width and delay from PPS
SCE data connectors will be female MDMs
SCE team will investigate isolating the USB-power-path into the Emulators (either a power-switch or single plug)

10. Emulator Team Test Support
SCE deliverables will be the Mini- and Full-Emulators and GSEOS deployment via downloads.
SCE Team will develop Hardware and Software User Manuals
User’s Manual will describe host PC configuration
User’s Manual will describe steps to complete a GSEOS, embedded firmware and embedded software upgrade
SCE Team will conduct HW/SW Requirements Review and Peer Review of First-Circuit Interfaces. Instrument Team participation is welcome.
SCE Team will maintain a website forum for SCE Users

11. Instrument Team Test Support
Instrument Teams will provide:
Host PC to run GSEOS
The Mini-Emulator will be designed and tested for compatibility to 64-bit Windows 7 (32-bit Windows 7 would be OK with the proper Opal Kelly drivers and minor GSEOS configs)
The Full Emulator will offer additional flexibility as requested
GSEOS support of SOC operations will offer additional flexibility as requested
SCE will use an Opal Kelly XEM6010, the PC will need to have driver version 4.x installed (current designing to 4.2.5)
Harnessing
Flight-rated power supply for use with flight-unit testing using the Full-Emulator
As needed for HW development , test and debug: Detailed analysis and compliance GSE (O’scopes, logic analyzers, SpW/UART protocol analyzers, EMI/EMC and EDTRD-specific testing)

12. Emulator Deliverables
Mini-Emulator earliest delivery is in June 2013
Full-Emulator earliest delivery is in April 2014
Emulator Schedule updates will be via the Project IMS
Requests for changes to emulator quantities should be sent through the applicable APL Instrument Manager.
Emulator spares will be held at APL and maintained by the Project Office. Coordination of spares will be through Patrick Hill.

13. RBSP Lesson Learned
Power Interface – PDU-style circuit breaker was omitted in S/C power service
Emulator Grounding with UUT and GSE – Clear grounding diagram is needed for all relevant configurations
Flight test requirements – Only the Full-Emulator with a in-cal external power supply should be used for flight
LVDS Interface ICs – ESD-protection is manufacturer specific and flight testing interfaces need to be compatible; use unscreened flight parts or verify compatibility of interfaces during transients and fault conditions
SCE standardization – develop emulators to minimize Instrument-specific customizations and features/add-ons
ICD Maturity – SCE/GSEOS can only be as current as the latest revisions of the ICDs and Requirements; continued communication is beneficial to everyone
SCE field support – RBSP emulators experienced field returns and in-process updates; Instrument teams should plan for these especially on the Mini-Emulator. Firmware and GSEOS SW updates will not require HW return(s).

14. Conclusion Instrument concerns Instrument-specific requirements
