Fault Mapper Pro®Telephone/Coaxial/Parallel
Cable Tester Graphical TDR
Model CA7026

The Fault Mapper Pro®Model CA7026
is a hand-held graphical TDR (Time
Domain Reflectometer) designed for
identifying and locating faults on
power and communication cables,
given access to one end only. The
Model CA7026 measures cable length,
and indicates the distance to cable
faults and terminations to a range of
11,700 ft or 3500m (user selectable), on
virtually any type of cable of two or more
conductors. The Model CA7026 shows
a reflection profile of the cable under
test as an oscilloscope-like trace on a

128 x 64 pixel graphical LCD. A
movable cursor can be aligned with
points on the trace; the distances
displayed will automatically update to
the cursor position.

The Model CA7026 has a selectable
impedance facility allowing it to be
matched to the cable under test. This
automatically eliminates the transmission
pulse from the display, enabling easier
identification of short range faults and
terminations.

The Velocity of Propagation (Vp) is
adjustable between 1% and 99%
enabling accurate calibration to the
cable under test.

The Model CA7026 incorporates an
oscillating tone generator that is
detectable with a standard tone receiver,
for use in the tracing and identification
of cables.

*Measurement accuracy of ±1% assumes the instrument setting for Velocity of Propagation (Vp) of the cable under test to be accurately set, and homogeneity
of the Velocity of Propagation (Vp) along the cable length. Accurate positioning of the cursor is also required.
