3M DYNATEL 965DSPA/SA ANALYZER WITH TDR REPAIRED 965DSP/SA Subscriber Loop Analyzer
The DynatelTM 965DSP/SA 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 Analyzerís 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.
