IVE DEVICES HAS BEEN USED. This technique allows the devices to be characterized in their actual working condition--inserted in the cable line-- without the perturbing influence of voltage and current probes. The report starts with the basic line theory and develops an understanding of the effect of shunt devices and the measurement of such effects using TDR. This section is fairly lengthy however, a good background is essential for the understanding of measurements made with this technique. In addition to the measurement technique itself, a special pulse generator was developed to provide the necessary pulse into 50 ohm lines. This pulse source is described along with the basic measurement procedure. Specific techniques and data are shown for a variety of shunt protective devices.
