Verify normal system operation and, where appropriate, measure the installed RF path's loss and match. RF checks assess signal performance, not full surge qualification.
How it works in practice
Record before-and-after conditions, including cable route and adapters. Use suitable low-power calibrated measurements with equipment safely isolated from external bias or transmitters. Investigate unexpected loss before attributing it to the protector; connector damage and water ingress can contribute.
Example and interpretation
An additional 1 dB loss beyond the expected path budget warrants checking connections and model suitability.
Checks before use
- Record baseline conditions
- Check normal bias operation
- Measure loss and match
- Inspect unexpected changes
Important limit
A successful RF sweep does not certify lightning survivability.
