The 4935A Transmission Impairment Measuring Set tests circuits for faults and qualifies circuits for voice, data, and broadcast service. In addition, with its 110kHz bandwidth, it performs the required tests to qualify the local loop for Digital Data Systems (DDS) up to 56 kbps. The 4935A performs measurements compatible with the Bell standards (BSTR 41009) and IEEE standards (IEEE 743-1984). The 4935A measures for level, frequency, circuit noise, noise-with-tone, signal-to-noise ratio, 3 level impulse noise (with tone), and noise-to-ground.

FEATURES:

• Level/frequency 20 Hz to 110 kHz
• Noise and noise-to-ground
• Noise-with-tone and signal-to-noise
• Three-level impulse noise
• P/AR available as an option
• IEEE 743-1984 North American Measurement standard
• Transmit/receive connectors: WECO 310
