All of your enabled masks are now listed on the
PSD tab page in the Mask parameter, for test
selection.
Result Details
The Results Details read-only page displays the WB
PSD Noise test results, in text and graphical format. If
an ESEL (Exchange Side Electrical Length) value was
set, it is also displayed. The graph can be viewed in
portrait and landscape modes, and maneuvered as
follows:

Cursor - press the left/right arrow keys to
decrease/increase the values by moving the
cursor. Press and hold the left/right arrow keys
to accelerate the cursor. Press
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.

1:1 resets the x-axis and y-axis limits to full
scale.

Landscape Mode function key allows you to
view the test results in landscape mode.
Whether the keyboard is on the right or left is

The Count function displays and updates results in real
time, for the length of time set in Test Duration or less

Termination is either Terminated, if the
termination resistance is internal to the unit, or
Bridging if additional termination resistance is
used to bridge onto live circuits with minimal
interruption.
Termination Resistance lists the resistance of
the dummy load connected to the line.
