摘要： A method for detecting failures in electrical cable assemblies is provided. A cable test instrument obtains frequency domain data representing electrical characteristics of a cable link under test. A number of connectors in the cable link under test is determined based on the obtained frequency domain data. An estimated location of each of the connectors along the length of the cable link under test is determined by the cable test instrument. The connectors are ranked in accordance with their respective contribution to detected failures in the cable link under test.

摘要： A hand held test instrument for testing a DSL line is provided. The test instrument includes an interface for unintrusive connection with the DSL under test. The interface is configured to capture Radio Frequency (RF) signals corresponding to a portion of a data stream transmitted by a communication device over the DSL under test. The hand held test instrument further includes a controller module configured to identify unique characteristics of the communication device based on the captured RF signals.
