AEMC CA7026 Data sheet

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.

Functional Displays

Typical Traces

The graphic display on the Model CA7026 will display the waveforms associated with the conditions found in
communication and other cables. The cursor may be moved to the left or right to indicate the distance to condition.
Additionally, the Velocity of Propagation and the impedance is also displayed.

Tone Receiver/
Cable Tracer
Model TR02

Model TR02

The Tone Receiver/Cable Tracer Model TR02 is a small, hand-held tracer that
will aid in the identification of tone carrying wires without piercing their insulation.
It has a self-contained amplifier and a rugged, moisture resistant mylar cone
speaker. When used in conjunction with the tone transmitter function of the
Models CA7024, CA7026 or CA7028, wire tracing and locating is quick and
efficient.

One button turns the unit on and, while it is depressed activates the receiver. A
volume control allows you to set the speaker loudness to a desirable level. An
audio output jack facilitates the use of an optional, commercially available ear piece
which inhibits the Model TR02’s internal speaker. This provides quiet operation
in office environments while allowing the operator to hear the signal clearly.

Model TR02 used to find cables in a panel.
