Wire map cable LAN network tester
In the event of opens and shorts, the Model CA7028 uses TDR technology to indicate if the fault is at the near end or the remote end of the cable, or if it is somewhere in between. It will then indicate the distance to the fault. The Model CA7028 has the ability to measure and indicate the length of the cable under test, using a Vp (Velocity of Propagation) set by the user, from a built-in library or manually. It will measure and report the length of all four pairs of wires in the cable under test. It also generates an audible tone that is transmitted into all four pairs on the cable under test. This can be used for cable tracing and identification in conjunction with a tone receiver.
