OneTouch Series II

Users Manual

The Network Assistant is preprogrammed with typical NVP values for CAT 3, 4, and 5 UTP cable. In addition, there are two user-definable Cable Types for you to enter your own NVP values.

Cable Termination

In addition to determining cable length, the TDR technique provides information on the kind of termination at the far end of the cable and the cable’s characteristic impedance.

The Network Assistant examines the polarity of the reflected pulse to determine if the cable end is an open or short, as shown in Figure 4-6. If the wire pair is perfectly terminated there is no reflection.
