DIAGNOSTICS & CORRECTIVE ACTION

How do we localize and resolve a failure?

Organize hypotheses, discriminating experiments, corrective actions, and regression evidence. Start with an engineering task or inspect the linked knowledge entities.

START / TASK ROUTES

Choose an entry point by the task to be completed.

Each route connects explanation, action, limits, and evidence; there is no need to learn the site structure first.

01RECOMMENDED START

Run the 150 MHz diagnosis

Move from hypotheses and A/B tests to evidence, root cause, corrective action, and regression.

Open task ↗02ENGINEERING ROUTE

Explore diagnostic cases

Reuse corrective-action patterns through frequency relationships, physical paths, and verification actions.

Open task ↗03ENGINEERING ROUTE

Inspect a structured case record

Review the failure, observations, experiments, root cause, side effects, and regression record.
