cursor and place it in the middle of the current
x-axis limits.
Zoom
references the middle of the x/y axis and
not the cursor position. Press the arrow keys
as follows:
o
Right = x-axis zoom in.
o
Left = x-axis zoom out.
o
Up = y-axis zoom in.
o
Down = y-axis zoom out.
Pan
- use left/right arrow keys to pan the x-axis
and the up/down arrow keys to pan the y-axis.

resets the x-axis and y-axis limits to full
scale.
12.7 Locator Tone
When
Locator Tone
is selected from the
Frequency
Tests
menu, a 577 Hz signal and a 983 Hz alternating
signal are sent separately for 200 ms each. The
sequence of this tone is repeated continuously until you
stop the test. A sinusoidal waveform is used to
generate these signals. Cable locators such as
Radiodetection’s RD8100 can detect 577 Hz as
standard and can also be programmed to locate 983
Hz.
Tone
The
Tone
function allows you to set the
Tone Power
and generate a pulsed tone on the line to trace a cable
pair at the far end.
Current Group
is the current test group name,
for example
Frequency Tests
.
Current Test
displays the test being
measured. Here you can switch to another test
from the given list. However, this action will
terminate the ongoing measurement test.
Tone Power
allows you to select either low or
high power for the
Locator Tone
.
Tone Frequencies
displays the frequencies of
the
Locator Tone
.
Termination Resistance
is a read-only value
of
600 Ω
.
Result
displays the Elapsed Time the locator
tone is being sent.
Test Status
displays the current state of
measurement or an error message.
To select the parameter values:
1. Press the up/down arrow keys to highlight the

3. Press
on a value to open a list box of
options.

to confirm the value.
12.8 TX/RX Tone
The
TX/RX
Tone tests allow you to generate tones and
measure the frequencies and levels of incoming
signals.
