Tools, Equipment, and Materials Provided

• CT100B TDR Cable Analyzer
• CT100-AK-BNC RF connector Kit
• CT100-AK-PSP MOHR MIL-DTL-38999 adapter kit

Procedures

Teams will be presented with problematic multi-component cable assemblies and be responsible for locating and identifying failure points using high-resolution TDR data. Faults may be intermittent, requiring the team to perform intermittent fault detection and location.

Tests

1. Discharge static from transmission cable using best practices
2. Select appropriate cabling and adapters from available harnesses
3. Instructor will identify appropriate device-under-test (DUT) from schematic
4. Locate, quantify, and diagnose failed component

Test 1: Identify bad antenna components

CT100B: Typical graphic for good antenna

Test 2: Identify bad engine harness (incorrect impedance due to mis-twist, aging effects, etc.)

CT100B: Typical graphic for multi-part harness

Test 3: Identify Bad connector or cable kink (bad splice, bad connectorization or bend radius)
