Product Description
Up for sale is a Subscriber Loop Analyzer manufactured by 3M. We do not have power cable to test so must be sold as parts or repair. Item has some surface imperfections from age, with normal signs of wear from previous use. Display screen has black squiggly lines on it. Includes only what is pictured.
3M Dynatel 965DSP: 0 to 300 V DC; 0 to 250 V AC; 0 to 110 mA; 0 to 900 MΩ
The 3M Dynatel 965DSP Subscriber Loop Analyzer is a microprocessor-controlled integrated test set that provide 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 965DSP 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
- 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 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
