Illustrative payload: 8 channels * 10000 samples/s/channel * 2 bytes = 160000 bytes/s = 1.28
Mbit/s before overhead. Specify simultaneity, accuracy and timestamps separately from 16-bit
representation.
Illustrative costs: standard USD 140/unit; custom USD 80/unit + USD 12000 NRE -> break-even
200 units; both USD 28000. Replace all inputs; include tooling, qualification, yield,
support and inventory.
Prototype / verification / qualification / pilot / acceptance milestones:
Every-unit production test coverage / sample qualification scope:
