DescriptionDynatel 965DSP 80-6108-6390-6 Subscriber Loop Analyzer | Complete testing of POTS and ISDN subscriber loops
OverviewThe 3M™ Dynatel™ 965DSP Subscriber Loop Analyzer is a microprocessor-controlled integrated test set that provides full-featured POTS and fundamental ISDN testing. The functions include fault location and repair verification on twisted-pair, quad and coaxial cable (utilizing capacitance bridge, resistance bridge and Time Domain Reflectometer (TDR) functions).The Dynatel 965DSP subscriber loop analyzer executes a wide range of individual tests, or performs automatic test routines as specified by the user to categorize and sectionalize problems. Specific tests and measurements performed by the unit include: Voltage – detects and measures the presence of exchange or foreign DC or AC voltages. Tone – provides a test tone for conductor identification; user-selected tones from 1 to 40 kHz for transmission measurements. Current – measures DC loop current. Ohms – measures conductor and insulation resistance up to 1000 megohms. TDR – full-featured TDR with user-selectable pulse widths, length, gain zoom, filter and Vp. Four modes of operation:Single trace – provides graphical representation of events on a pair.Dual trace – allows active comparison of two traces.Differential – displays difference between two circuits.Crosstalk – displays the crosstalk from one pair to the other. Resistance fault location – displays distance to fault. Opens – locates opens at distances up to 100,000 ft. (30 km). Splits – locates splits on paired cable. Ringer count – counts the number of ringers on a particular loop. Load coil count – indicates the presence of load coils in a loop circuit. Wideband loss – loss measurements to 200 kHz for pre-qualifying ISDN and HDSL. Loss – measures voice band loss. Noise – measures noise metallic and noise to ground in dBrnc. Longitudinal balance – provides active measurement of line balance.
Flexible, Practical FeaturesThe 965DSP subscriber loop analyzer is designed for functionality and ease of use. Features of the unit include: IR port - infrared port for downloading future software programs. Self-calibration – internal instrument calibration and setup procedures. Graphical user interface – user-friendly, icon-based display of test results. Replaceable five color-coded banana jacks for test connections. HELP function – an internal help menu provides information as needed during operation. Telephone – internal telephone or “talk set.” Rechargeable nickel metal hydride batteries – with battery charger, plus alkaline battery holder. Modular hardware and software design – for easy upgrades, investment protection. Backlit high resolution/high contrast LCD display.
Rugged, Weatherproof DesignThe hand-held 965DSP test set is housed in a lightweight, ergonomically designed case for portability and ease of handling. The unit is weather-resistant and weighs only 3.3 pounds (1.5 kg).
