3M DYNATEL 965DSPA/SA/ADSL SPECTRUM ANALYZER W/ADSL REPAIRED 965DSP/SA/ADSL Subscriber Loop Analyzer
The DynatelTM 965DSP/SA/ADSL Subscriber Loop Analyzer delivers all of the multi-function capabilities of the Dynatel 965DSP and provides a Spectrum Analyzer and E, F and G noise-weighted filters. The Spectrum Analyzer enables the operator to view the wideband (10 kHz to 1.8 MHz) spectrum and identify spectral interferers such as noise generated by other services. The 965DSP/SA Subscriber Loop Analyzer’s E, F and G noise-weighted filters perform tests to determine metallic noise in ISDN/IDSL, HDSL and ADSL services. Sources for noise can include in-band circuit or switching noise from network equipment, as well as cross-talk components of other service types appearing on nearby pairs. Tests determine the metallic noise on a pair by terminating the pair with its characteristic impedance and measuring the differential noise appearing across the conductors. It also has an ADSL modem to allow interaction with the ADSL circuit including testing upstream and downstream speeds and ping tests.
