Advanced Measurement Functions
The 720 DSP includes all of the following advanced measurement functions standard:
Frequency Domain Reflectometer
This feature enables the 720 DSP to provide a simple, convenient and accurate tool
for determining the distance to cable faults by sending a sweep into the cable and
analyzing the complex reflected wave to determine the distance to various sources
of reflection (opens, shorts, splitters, etc.). The reflecting events are indicated on a
distance versus amplitude display, and markers are used to identify the distance to the
source of the reflection, and the return loss at that point.
