    - Recommended minimum cable length for testing is 30m in order to get meaningful measurements of cable characteristics.
- Connect Permanent Link Adapter to TestPro.
- Choose appropriate Cat5e/6/6A PL limits.
- Run Single Ended Autotest.
- Verify NEXT & Return Loss performance of Cable under test.

This test is helpful to qualify Cable Drums before using them for Channel/PL installations.
