Tracing Tone
Tracing Tone
The Tracing Tone pane allows you to
configure and place a pulsed tone on
the line to trace a cable pair at the far
end. When Tracing Tone is selected
from the VF Tests menu, the tracer
tone sends a 577 Hz signal for the first
80 ms, then the signal is turned off for
80 ms, turned on for another 80 ms,
and off again for another 320 ms. The
sequence of this tone is repeated
continuously until you stop the test. Sinusoidal waveform is used to
generate the 577 Hz signal.
Each parameter and button on the pane is described below.
