dB
Use this function to measure Loss, Noise, Longitudinal Balance, or Wideband Loss.
Press the [Up] or [Down] keys to move to a test. Press the [Enter] key to accept the choice.
For Loss, Noise and Longitudinal Balance, you will first be asked to dial a number (for a quiet line, milliwatt line, etc.) before starting the test.
See “Talk Set” on page 38 for more information on dialing numbers. The “Dial Noise” and “Dial Longitudinal Balance” screens appear the same as above, except for the screen titles.
Separate lists of phone number are kept for each function. Press the [Right Arrow] key to measure Loss after the test line answers.
