respective detection levels, and
Elapsed Time
.
Here the pass/fail status is for the

-level
only.

Noise Result Graph
The
Noise Result Graph
page displays the pass/fail
status and results in graphical format for the following
noise tests:
Power Influence
measures the effects that 50
Hz and 60 Hz powerline (AC Mains)
interference has on the circuit under test.
WB PSD Noise - Max PSD
and frequency and
RMS Noise
values differentiating the
Current
trace from the
Peak
hold. This test can be
viewed in
Landscape Mode
.
To select a test:
1. In the
Select Test
parameter, press the

o
Zoom
references the middle of the x/y

not
the cursor position. Press
the arrow keys as follows:
Right = x-axis zoom in.
Left = x-axis zoom out.
Up = y-axis zoom in.
Down = y-axis zoom out.
o
Pan
- use left/right arrow keys to pan
the x-axis and the up/down arrow keys
to pan the y-axis.
o
1:1
resets the x-axis and y-axis limits
to full scale.
o
Return To Test

function keys to display the previous
function keys.
Landscape Mode
function key allows you to
view the
WB PSD Noise
results in landscape
mode. Whether the keyboard is on the right or
left is dependent on your preferred
Landscape
Mode Settings
configured in
Application
Settings/General
.
Frequency Result
The
Frequency Result
page displays results and
