Megger-TDR2050

The Megger® TDR2000/3, TDR2010 and TDR2050 are state of the art, dual channel, high resolution, compact Time Domain Reflectometers with a colour screen for locating faults on paired metallic cables. All TDRs in this series have a minimum resolution of 0.1 m / 0.3 ft and a 20 km / 65 kft maximum range depending on the velocity factor selected and the cable type. Various output impedances are available (TDR2000/3 and 2010: 25, 50, 75, 100, 125 ohm + AUTO. TDR2050: 25, 50, 75, 100, 140 ohm + AUTO) and an auto impedance matching feature. The velocity factor can be set between 0.2 and 0.99 to meet any cable test requirements.

FEATURES AND BENEFITS
The TDR2000 series have a large, high resolution, colour, 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 selected 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 full 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 colour schemes give the graphical display a vibrance, aiding the user in identifying key events on the trace.

600 V CAT IV input protection
TDR2050 is the first TDR in this class to include a builtin 600 V 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 strength 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, built into the TDR2050, 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.
