Terms and Descriptions
The table below defines the terms used throughout the manual and
provides information to assist you with proper operation and
understanding of the unit and its functions.
Term
Description
Spread Spectrum Time SSTDR is a patented technology that allows
Domain Reflectometry for diagnotic testing on cables without
(SSTDR)
interference from voltage.
Open Fault
Typically an unterminated wire, broken wire,
or bad connection.
Short Fault
Two wires making contact or connected
together (closed circuit).
Fault Location Testing
Testing for faults that are persistent, (either
a hard short or open which do not change
with time).
Live IFD Testing
Intermittent Fault Detection (IFD)
continuously tests for a fault on live or unenergized cables that can occur randomly
and not persistent.
Live Sweep Testing
An intermittent fault detection function that
is used to locate intermittent fault conditions
on extremely long energized cables (≤ 6
kilometers), but also retains the ability to
detect short and medium distance faults.
VOP
Velocity of Propagation (VOP) is the speed
at which a signal travels through a cable,
measured relative to the speed of light. For
most cables, this is about 66% the speed of
light.
