  • Fault diagnosis using built-in test equipment
  • Trouble analysis with diagnostic computer programs
  • Technical manual interpretation for equipment restoration

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Preventive and corrective maintenance of the AN/GRN-33(V), including test-equipment and software-assisted fault diagnosis, transfers directly to electronic equipment repair.

How to prepare: Practice diagnosing a commercial electronic unit from its service manual and documenting the fault, repair, and verification results in a maintenance log.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Electrical and Electronic Engineering Technologists and Technicians

Experience using general and special-purpose test equipment to diagnose and restore electronic guidance systems supports electronics test and maintenance technician work.

How to prepare: Complete a hands-on electronics lab that uses schematics and test instruments to diagnose component or assembly faults and record performance measurements.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.
  • Read blueprints, wiring diagrams, schematic drawings, or engineering instructions for assembling electronics units, applying knowledge of electronic theory and components.
