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.

Key Saleable Features

Cable Fault Location up to 3500m (11,700ft)
Th
e 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.
