600 V CAT IV input protection
TDR2050 is the first TDR in its class to include a built-in 600V CATIV input protection filter. The ability to connect to potentially live circuits means a more flexible instrument suited for a wider range of applications.
Trace storage
100 internal trace memories provide for the storage and recall of test results. The traces can be recalled to the display for analysis or compared with an active display to aid in fault location. Alternatively the stored results can be downloaded to a computer, via the USB port, using the TraceXpert software and USB lead provided.
Step TDR function
The Dead Zone effect of a standard pulse TDR can mask near-end faults and make them undetectable. The addition of a step function on the TDR2050 eliminates this problem.
Step TDR technology means that the signal is injected at full stength and stays there until a disturbance is detected. This makes step TDR technology perfect for detecting near-end faults that standard pulse TDRs can miss.
Distance dependant gain
This feature eliminates the drop off of signal attenuation on longer lines by gradually increasing the gain along the returned signal, enabling a more even representation of the relative attenuation at all points along the trace.

The Megger TDR2050 is a state of the art dual channel, dual trace time domain reflectometer ideal for locating faults on paired metallic cables. It is the first TDR in its class to have 600V CATIV input protection filter built in, giving the ability to connect to known live lines. This is particularly useful for detecting illegal taps without having to power down the line.
The TDR2050 has a minimum resolution of 0.1 m / 0.3 ft and a 20 km / 65,000 ft maximum range depending on the velocity factor selected and the cable type.
Various output impedances are available (25, 50, 75, 100, 125, 140 ohms) and an auto impedance matching feature. The velocity factor can be set between 0.2 and 0.99 to meet any cable test
requirements.

The TDR2050 has a large, high resolution, color, WVGA display with easy set up features. Directional control buttons, together with soft keys, provide intuitive and easy operation for the user. An AUTO selection option ensures that the most effective parameters are chosen depending on the range required, aiding rapid diagnosis of the TDR trace. The ability to manually override the auto function allows fine tuning to enable identification of hard to
determine faults.
Dual trace and dual cursor capabilities allow full flexibility, giving the operator complete control and instant indication of distance between two points. A trace comparison feature also allows close examination between trace conditions. Extra high resolution, together with a white-light backlight, user definable color schemes give the graphical displa
