The Dynatel™ 965DSP Subscriber Loop Analyzer with Spectrum Analyzer performs a wide range of tests and automatic test routines. Test functions include fault location and repair verification on twisted-pair and drop cables.
The Dynatel Subscriber Loop Analyzer 965DSP/SA delivers all the multi-function capabilities of the Dynatel 965DSP and provides a Spectrum Analyzer and E, F and G noise-weighted filters. The Spectrum Analyzer test function enables the operator to view the high-frequency communications spectrum and identify spectral interferers such as crosstalk noise generated by other services.
The 3M Dynatel 965DSPSubscriber 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 965DSPsubscriber 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 exchang 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 u 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.
The Dynatel 965DSP/SA/ADSL Subscriber Loop Analyzes features an Alcatel MTK-20150 ADSL modem chipset in the proven 965DSP platform. The Dynatel 965DSP/ADSL provides the ability to perform active ADSL testing to address the growing number of residential and business ADSL customers. It delivers all the multi-function capabilities of the 965DSP plus the testing functions of the new ADSL modem. The 965DSP/SA/ADSL adds comprehensive DSL parametric measurements to this integrated solution. Extended loss measurement ranges, spectrum analyzer and E, F & G filtered wideband noise measurements complete this comprehensive family of rugged loop testers.
The Dynatel 965DSP and 965DSP/SA/ADSL test sets are housed in a lightweight, ergonomically designed case for portability and ease of use. The units are weather resistant and weigh only three pounds (4.5 lbs. with test leads and soft case). Preserving the rugged dependability of all Dynatel products, the /ADSL option incorporates an innovative design that adds a durable spacer element to the current 965DSP molded plastic case. This spacer permits easy and robust expansion of the new circuit board in the existing test set.
Dynatel 965DSP Specifications:
Product will incorporate all the features of the Dynatel 965DSP and/or 965DSP/SA Subscriber Loop Analyzers at the accuracy currently specified for these products (see 965DSP family product documentation). ADSL Datalink capability is limited to link synchronization. No PING or data application capability is provided. Modem will initiate a connection with the far-end under operator command. Status messages indicating link progress will be returned.
