Telephone Line Analyser The Agilent / HP 3770B is designed for audio data line characterization to CCITT standards. The HP 3770B makes, in one combined unit, all of the routine maintenance measurements listed in CCITT Recommendation M.1060 for high speed data lines. The HP 3770B measures group delay, attenuation distortion, and absolute level in the frequency range 200 Hz to 20 kHz. It has automatic ranging, zeroing, and synchronization, with simultaneous LED read-out of measurement result and frequency. The sender and receiver are combined in a single, rugged, portable unit. The HP 3770B also measures weighted noise, noise-with-tone and impulse noise. A crosstalk measurement is available as an option. Further, an optional slave facility for group delay and attenuation distortion measurements allows the measurement results for both directions of transmission on a 4-wire circuit to be displayed at one end of the circuit.
