dB
Use this function to measure Loss, Noise, Longitudinal Balance, Wideband Loss, or perform a Level Trace.
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.
Connect the test leads as indicated on the left side of the screen.
See “Talk Set” on page 135 for more information on dialing numbers. The “Dial Noise” and “Dial Longitudinal Balance” screens are the same as shown above, except for the screen titles.
Separate lists of phone numbers are kept for each dB function. Press the [Right] key to bypass the dialing process and manually measure.
