TX2003 Features

The TX2003, 6k (19,000ft) range Time Domain Reflectometer weighing only 350 grams (13oz), fits neatly into the hand. With its 128 x 64 pixel backlight, scratch resistant display, provides accurate and easy to read fault locations on metallic cables. With a 3 nano second pulse, rise time "near end" cable faults can be clearly identified without the need to surpress the transmitted pulse. Housed in a rugged IP54 rated ABS enclosure, the TX2003 is suitable for outside use.

Using predetermined gain and pulse widths for each range setting and with only 4 control buttons, all major operating and setting parameters can be easily accessed. A 6km cable run can be scanned in seconds, allowing the operator a view of the cable run, yet arriving quickly to the fault. By using the TX2003 scan lock facility, the cable can be continually scanned or the trace held for closer analysis. To enable the TX2003 to test all metallic cables, four user selectable output impedances are provided 25, 50, 75 & 100 ohms.

Faulty cables may be traced using the TX2003 warble tone feature, an oscilating tone is injected into the suspect power or transmission line and by using a commercially available tone tracing probe, the suspect line can be identified.
