When Mechanical Float Becomes an Electrical Failure
How a floating coaxial contact, assembly stress, and cable load combined to trigger intermittent 6 GHz video dropouts.
The continuity test passed. The link did not.
Static continuity passed, but directional cable loading exposed two independent weaknesses at the same coaxial interface.
The dimensions passed. The image did not.
Dimensions may pass individually while datum selection and tolerance stack-up move the functional interface.
The video never froze. It just arrived late.
How a connector-insertion condition separated two repeatable host-reported USB states.
