Dual Trace
Dual Trace is used to compare two coaxial circuits at the same time (usually a faulted and a good circuit).
Connect the TDR test leads to the (Red and Black jacks) and connect the second TDR test lead set (Blue and Yellow jacks) to the reference circuit. This mode is valuable when testing a system with multiple coaxial wires serving the same system.
