Overview

A CASS Family of Testers RADAR IMA Technician operates CASS testers and associated automated test equipment to isolate faults and maintain aircraft radar units under test. The technician uses RF and high power configurations to analyze circuits, make adjustments and repairs, and verify the serviceability of airborne radar systems.

Minimum clearance: Secret

Core Skills

  • RF and high-power automated testing
  • Circuit-level fault isolation and repair
  • Airborne radar serviceability verification

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.

Avionics Technicians

CASS radar fault isolation, circuit analysis, repair, and serviceability verification transfer directly to avionics component troubleshooting and repair.

How to prepare: Build a resume example tracing a radar component from failed automated test through fault isolation, repair, and successful verification, and target avionics bench-repair openings. For airline openings, check the employer's mechanic-certificate requirement: air carriers often require it, but it is not an FAA requirement for every airline mechanic job.

What the civilian work involves
  • Test and troubleshoot instruments, components, and assemblies, using circuit testers, oscilloscopes, or voltmeters.
  • Adjust, repair, or replace malfunctioning components or assemblies, using hand tools or soldering irons.
  • Keep records of maintenance and repair work.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Automated test equipment operation and circuit-level radar diagnosis provide a foundation for diagnosing, repairing, and testing industrial electronics.

How to prepare: Complete a hands-on industrial electronics troubleshooting course that includes equipment setup and post-repair functional testing.

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
