Cover two critical performance parameters: NEXT, and RL.
The highest level of requirements for the cable performance. A network patch cable passing the patch cord testing usually has higher performance and is more durable.
Cover a number of measurements: NEXT, PS NEXT, ACR-F, PS ACR-F, ACR-N, PS ACR-N and RL.
Measure the connection between two devices, including any patch cable and equipment cords to confirm the end to end system performance.
