Time Domain Reflectometer (TDR)
Used for testing Coax cables
- Sends pulse of energy down the cable
- Signal returns to TDR and detects reflections made by discontinuities
Causes of changes in Impedance
- Cracks
- Kinks
- Shielding damage
- Short circuits
- Moisture ingress
- Dielectric damage
- Open circuit
Sensitive to impedance
Changes in impedance displayed as hills and valleys on graph
Short circuit will reflect a negative pulse
Open circuit will reflect a positive pulse
