2.3.6-1-3 Ensure requirements traceability from EMC (Electromagnetic Compatibility) system level requirements to unit level procurement specifications Phase A | Phase B | Ensure requirements traceability from EMC (Electromagnetic Compatibility) system level requirements to unit level procurement specifications before procurement of units. Unit procurement usually starts short after the preliminary design review. This is required to ensure traceability from system requirements to unit requirements. The system level requirements have precedence over the unit level requirements. This level should have the actual unit level EMC requirements, EMC design requirements, EMC verification requirements including inspection, Final required as exit criteria from (PDR).

2.3.6-1-4 Ensure system constraints on Electromagnetic Compatibility (EMC) design to ensure EMC design meets system requirements Phase A | Phase B | Phase C | Ensure system constraints on EMC design considers mission requirements, heritage hardware capability, weight, structural, thermal, life issues, reliability, radiation, signal integrity, parts/materials/processes, etc.to ensure design meets requirements. Draft constraints should be identified by System Requirements Review. Final system constraints should be identified by PDR. Ensure EMC design meets each systems constraints as exit criteria from CDR.

2.3.6-1-5 Ensure heritage hardware and qualified by similarity hardware evaluated for compliance with EMC (Electromagnetic Compatibility) requirements Phase A | Phase B | Ensure heritage hardware and qualified by similarity hardware evaluated for compliance with EMC (Electromagnetic Compatibility) requirements. This includes any hardware that will be procured without requiring EMC qualification or acceptance testing at the unit level. The final evaluation showing margin should be done by the Preliminary Design Review. The task completion may change to system requirements review if there is significant program cost and schedule risk being taken by delaying the task. This is phased for no mission risk.
