Abstract:
1. A method to test electrical characteristics of a port-under-test, the method comprising: establishing a communication link to the port-under-test using a test cable connected between the port-under-test and a test port, having a medium dependent interface (MDI) and an integrated transceiver having a diagnostic digital receiver; configuring the diagnostic digital receiver; probing at least one diagnostic digital receiver signal originating from the port-under test over at least one wire pair within the test cable while maintaining the communications link to the port-under test; processing the at least one probed diagnostic digital receiver signal into a measurement; adjusting the measurement to remove from the measurement at least one predetermined power characteristic associated with at least one of: the test cable; the MDI; and the diagnostic digital receiver; and comparing the adjusted measurement to a predetermined standard for the port-under-test.
