amd19f.eps
A
The magnitude of crosstalk. Crosstalk levels plotted are
adjusted to compensate for insertion loss. This means the
plot represents the magnitudes of signals at the crosstalk
source.
B
The beginning and end of the cabling under test. For a
permanent link, the plot shows some of the permanent link
adapter cable before and after the cabling under test.
C
Horizontal and vertical magnification levels for the
plot. In zoom mode, use
BC and AD to
zoom in or out at the cursor’s location.
D
The distance to the end of the cabling.
E
The cursor and the distance to the cursor from the
tester. In cursor mode, use
BC to move the cursor.
F
The crosstalk magnitude at the cursor's location.
G
Shows the crosstalk plots by pair. Press I to return
to the plot of all pairs.
H
Toggles the display between zoom and cursor
modes.
I
Sets or clears the measurement marker. See J.
J
The distance between the measurement cursors.
To use the measurement cursors (with the plot in
cursor mode):
1 Press
J Clear Mark if necessary; then use BC
to move the cursor to the beginning of an area
of interest. Use
AD to zoom in on the
area if desired.
2 Press
J Set Mark; then use BCto move the
