DTX CableAnalyzer Measurement Accuracy
The DTX CableAnalyzer testers are guaranteed to meet the Level III accuracy
requirements at Cat 6 permanent link and channel pass/fail limits. Refer to the DTX
CableAnalyzer Series Technical Reference Handbook for details.
Patch Cord Test Configuration Measurement Accuracy
The charts in Figure 4 show NEXT and return loss measurement accuracies for the patch
cord test configuration. The results were computed using the methods defined in
standards applicable to field tester requirements. The accuracies shown reflect the
accuracy of the measurement circuitry, excluding variability caused by the adapters’
connectors.
