Used BIDDLE MEGGER TDR500 #9109874 for sale

BIDDLE MEGGER TDR500 is a state of the art electronic test equipment designed to accurately measure long and short high impedance cable lines, medium and low impedance data cable lines, and circuitry. TDR500 uses pulse-detection-based time-domain-reflectometry (TDR) technology to assess the physical characteristics of cables and circuits. BIDDLE MEGGER TDR500 uses four modes of operation to perform its testing: single-ended DC, differential-ended DC, single-ended AC, and differential-ended AC. Its single-ended DC mode allows for testing of cables and circuits that have a DC return path, such as an earth ground. The differential-ended DC mode is used for testing balanced circuits, such as telephone lines. The single-ended AC mode is used to measure the impedance and capacitance of unbalanced transmission lines. The differential-ended AC mode allows for measurement of differential impedances of balanced transmission lines. TDR500 offers high-accuracy performance with a basic accuracy of 0.1 percent. Using the differential AC or DC modes, accuracy is increased to 0.02 percent. Input impedance can be adjusted between 5, 10, 20, and 50 ohms, and user-selectable frequency ranges from 20 MHz to 70 GHz allow for the testing of cable and circuit ranges from a few meters up to hundreds of kilometers without external signal splitters or couplers. The Megger BIDDLE MEGGER TDR500 also includes an oscilloscope with a dynamic range of 12-bit resolution, allowing for the accurate detection of impedance changes within a cable or circuit. The integrated 20MHz scope with selectable reference voltage allows for an additional visual representation and debugging of any electrical anomalies that may be encountered. Additionally, the user-friendly graphical interface allows for the visualization of time domain representations of impedance results. Finally, TDR500 features an automated "auto-identification" procedure which allows it to detect and display the impedance of cables which may be difficult to identify. These include communications lines such as T1, E1, Ethernet, and all others. BIDDLE MEGGER TDR500 is a precise, accurate, and high-performance test equipment device for diagnosing faults in cables, circuits, and electronic systems. The range of modes available, accuracy, oscilloscope, and auto-identification features make TDR500 an ideal choice for professional and hobbyist engineers alike.
