Introduction
The
TX2002 is a professional Graphical Time Domain Reflectometer designed
to detect and locate faults on copper communication cables up to
a distance of 3500m (11,700ft). In addition to the TDR capabilities
of the TX2002, a built in tone generator (oscillator) can be used
to transmit a warbling tone into the cable, or pairs within the
cable, enabling detection, tracing, and pair identification using
a standard probe receiver.
The combination of these two functions
within one cable fault locating product enables the communication
engineer to reduce the number of separate test instruments required,
and therefore provides a more cost effective and convenient solution.
The TX2002 is housed in a rugged,
custom designed enclosure, manufactured from flame retardant ABASE,
and incorporating dust and waterproof protection to IMP 54 to ensure
it meets the tough demands of field use. The TX2002 is also approximately
half the size of competitive units making it more convenient to
carry and use.
With UK list price of £499.00,
the TX2002 sits at between half and two thirds the list prices of
the closest competitive products, and contains the additional toner
function, not currently available in any competitive units.
The TX2002 is aimed
at all communications engineers and technicians, telecom fault teams
and linesman, and contractors to the communication industries.
More broadly, target
end users include Telecom Companies (RBOC's, CLEC's, PTT's, etc.),
Cable Television (CATV) and Cable Internet Service Providers, as well
as Government and Military organisations.

Saleable Features
Cable
Fault Location up to 3500m (11,700ft)
The TX2002 can locate the presence
of cable faults, including shorts, opens, taps, splices, water ingress
and other impedance anomalies, on copper communication cables up
to a distance of 3500m (11,700ft)
Suitable for all types of Communication Cable
The TX2002 has selectable 50, 75 and 100 Ohm impedance ranges
making it suitable for use on all types of metallic communication
cable including Coaxial and Twisted Pair. Velocity of propagation
is variable between 1% and 99%, in 1% increments.
Auto Ranging Scale linked to Cursor Position
The TX2002 has five measurement ranges, the most appropriate
of which is automatically selected by the instrument dependent on
the position of the cursor. This function reduces the time spent
in the field locating the cable fault or anomaly.
Built in Tone Generator (Oscillator)
With a built in tone generator, injecting an oscillating signal
between 810Hz and 1110Hz onto the cable under test, the operator
can trace the cable and also identify pairs within a bundle, using
a standard tone probe. This function removes the need for a separate
toner, which is both more convenient and cost effective.
Single Shot or Continuous Sampling Output Pulse
For simple faults the TX2002 can be used in Single Shot mode where
a test pulse is only transmitted each time a cursor key is pressed.
This function conserves battery life. For more elusive faults the
test button can be held down, whereby the TX2002 will transmit 6.7
test pulses per second. This rate is 6.7 times that of most equivalent
competitive products, and makes the TX2002 more likely to identify
intermittent faults.
Ultra-Bright 64 x 128 Electroluminescent LCD
The TX2002 features
an ultra-bright 64 x 128 electroluminescent LCD ensuring that the
instrument display is clearly visible under all lighting conditions
and with adequate pixel resolution to ensure accurate fault location
Built into a Tough Water & Dust Proof ABS Enclosure
The TX2002 is built into a custom designed ABS enclosure capable
of withstanding a drop of 1m onto concrete. It also incorporates
an impact resistant ABS display window and is protected against
the ingress of dust and water to IP54. These qualities ensure the
suitability and survival of the product under extreme field conditions.

A Short Note on
TDRs
The TX2002 is used
for cable fault locating on virtually all types of cable including
twisted pair, coaxial, and parallel conductor.
How?
The TX2002 transmits pulses
of a known shape and amplitude into one end of a cable that travel
along the cable at a speed determined by its velocity of propagation.
Vp is a ratio of the speed of light.
As the
pulses reach impedance changes in the insulation of the cable, indicative
of a fault, reflections are caused that travel back along the cable
and are identified by the TX2002.
The size, shape and general nature of the reflected pulses indicate
the type of fault encountered, and the time taken for the pulse
to be reflected enables an accurate measurement of distance to the
fault to be determined.
Why?
Continuity and performance
of service of modern communications systems is of paramount importance,
and all new installations and modifications to existing installations
must be tested to ensure trouble free operation. Additionally, in
the case of a fault in the cable infrastructure, it is necessary
to identify, locate and rectify the situation in as little time
as possible, ensuring rapid return of the service.
These products are used
by:
Electrical, Communication
and Telecommunication Engineers and Contractors for testing cable
installations as part of a routine preventative maintenance programme.
In addition, during, or after work on, all new cable installations
and modifications to existing cable installations, tests can be
made to ensure performance criteria are met.
Personnel
involved in the location of cable faults as part of a responsive
or routine maintenance programme.
Electrical Inspectors performing quality checks following work on
all new cable installations, and modifications to existing cable
installations.
