Keysight 4945A Transmission Impairment Measuring Set

PRODUCT SPECS

(From Used-Line T&M Specifications )
Status Discontinued
Alternative No replacement.

The HP 4945A transmission impairment measuring set provides the complete set of measurements needed to quickly isolate faults and qualify circuits for voice, data, or broadcast transmission up to 110 kHz. All measurements are compatible with Bell standards including the ability to test local distribution loops for Dataphone Digital Service (DDS) to 56 kbps.
