HP 4934A transmission impairment measuring set (TIMS) increases installation and maintenance productivity for telephone companies and service providers through its ease-of-use, portability, and ruggedness. Hewlett Packard offers versions of the HP 4934A that perform measurements to either IEEE 743 or CCITT specifications, including:

• Level/frequency up to 110 kHz
• Noise and noise-to-ground
• Noise-with-tone and signal-to-noise ratio
• 3-level impulse noise
• P/AR (North American version only)

Battery power is available as an option.

HP 4934A Covers a wide range of analog circuits with its 1-110kHz bandwidth, choice of C-message, 3kHz flat, 15kHz flat, program and 50kBit filters, and a choice of impedances. Can also help to verify telephone company tariffed parameters and work with other TIMS or automatic test equipment in the telephone network.
