Respect the cable's minimum bend radius and avoid abrupt strain near connectors. Bending can alter loss, phase or mechanical integrity.
How it works in practice
Use the assembly's installation and repeated-flex limits, which may differ. Keep cable routing stable during sensitive measurements and strain-relieve moving paths. If the measurement changes when the cable moves, compare against its phase and flex specifications rather than assuming the device under test changed.
Example and interpretation
A phase-sensitive VNA measurement can shift when a cable is repositioned after calibration.
Checks before use
- Read bend limits
- Keep routing stable
- Support connector ends
- Recheck after movement
Important limit
Do not use a universal bend-radius rule for every RF cable.
