TDR Test Status Status OK Status: Terminated Length: 92 (+/- 1) meters, Status: Shorted Length: 93 (+/- 1) meters, Status: Open Status: Impedance Mismatch Definition TDR test is complete, no fault is detected on the cable, and the test is terminated A short is detected on the cable. The location, in this example 92 meters, of the short is accurate to plus or minus one meter. An opening is detected on the cable. The location, in this example 93 meters, of the open is accurate to plus or minus one meter. There is an impedance mismatch in the cables. Usage Information Related Commands If the TDR test has not been run, an error messages is generated: %Error: Please run the TDR test first tdr-cable-test Run the TDR test.
