• Basic analog tests to isolate faults and to qualify circuits for voice, data, and broadcast service
• Compatible with the Bell standards (BSTR 41009) and IEEE standards (IEEE 743-1984)
• Measurement: Level, frequency, circuit noise, noise-with-tone, signal-to-noise ratio, 3-level impulse noise (quiet or tone), noise-to-ground, P/AR (option)
• Filters: C-message, 3 kHz flat, Program, 15 kHz flat, 50 kbit, 1010 Hz notch

Options:

The 4935A is a Transmission Impairment Measuring Set (TIMS) which measures widebａnd data and voice impairments. The frequency range over which measurements are made is 20 Hz to 110 kHz, in steps of I, 10, 100, 1000, or 10,000 Hz. There are four permanently stored, fixed frequencies -404, 1004, 2804. and 2713 Hz. Any other four frequencies may be temporarily assigned and stored by the user.
