10.2.10 Round Trip Delay

Round Trip Delay Results

The Round Trip Delay (Propagation Delay) measurement works by sending a test pattern. A errors is transmitted in the pattern.

The time it takes for the error to reach the receiver is the propagation time through the network.

Select SONET as TX/RX standard.

View the Round Trip Delay of a looped back signal.

Set check box on Setup RX pattern to Out-of-Service.
