Norristown, Pa. March 2018 – Megger now offers an advanced dual channel time domain reflectometer that can detect illegal taps without having to power down the line being tested.  The TDR2050 has a built-in 600V CATIV input protection filter, giving it the ability to connect to known live lines.

Easy to use equipment
This time domain reflectometer features a large color WVGA display with easy set-up features.  Directional control buttons and soft keys provide both intuitive and easy operation for the user. A built-in AutoFind mode allows for speedy identification of faults.  One press of the AutoFind key automatically adjusts the range and gain, while positioning the cursor to the first major event on the cable.  Press the key again and the cursor jumps to the next detected disturbance.

Perfect for locating faults on paired metallic cables by electrical service contractors, telecommunications technicians as well as cable television companies, the TDR2050 includes an auto selection option to ensure that the most effective parameters are chosen depending on the range required, aiding rapid diagnosis of the TDR trace. A manual override on the unit allows for fine tuning to enable identification of hard to find faults.

Trace tagging made easy
The TDR2050 features dual trace and dual cursor capabilities allowing for full flexibility, giving the operator complete control and instant notification of the distance between two points. A trace comparison feature allows for close examination between trace conditions.

The unit’s trace tagging function is saved into Megger’s TraceXpert software which gives full control over downloading, reporting and uploading of saved trace results. Up to 100 trace memories can be saved into the unit’s trace storage and later be recalled to the display for analysis or can be compared with an active display to help find a fault location.  These results can also be downloaded onto a computer via a USB port.

Megger’s TDR2050 includes a step TDR function that eliminates the Dead Zone effect.  This is when a standard pulse TDR can mask near-end faults and make them undetectable.  Megger’s step TDR technology allows for a signal to be injected at full strength and stay there until a disturbance is detected, making step TDR technology perfect for detecting near-end faults that standard pulse TDRs can miss.

Rugged, versatile test instrument
This rugged, IP54 rated time domain reflectometer features five output impedances, including 25 Ω, 50 Ω, 75 Ω, 100 Ω and 125 Ω and a velocity factor ranging between 0.2 and 0.99 to meet any cable test requirements. The unit has a minimum resolution of 0.1 m/0.3 ft and a maximum range of 20 km/65,000 ft depending on velocity factor selected and type of cable being tested.
