To expand the DSO Time displayed, press the left-mouse button down and drag the
cursor of the region to expand. The DSO will highlight the region. Release the left
button.
To return the DSO to normal display, double click the left- mouse button in the
expanded region.
At the bottom are the settings that let you change digital oscilloscope display. You
can also select the digital signals to view.
Any combination of the digital signals can be selected or deselected depending on
your interest. Additionally, any one of the digital signals may be used as the Trigger
in the Trigger Options tab, where trigger options include
Continuous
or
Manual
triggering.
Analog Trace
The upper trace of the digital oscilloscope can display any of the following
reconstructed analog signals:
•
Energy
– displays the reconstructed trapezoidal shaped pulse output from
the slow shaper that has been derived from the incoming tail pulse.
•
Fast Shaper
– displays the initial signal produced by the incoming
energy event detected by the fast discriminator.
•
Fast Threshold
– displays the current DC level representing the lower
level threshold of the fast discriminator. This value will vary when the
threshold mode is set to
Automatic
.
•
ADC
– displays the reconstructed tail pulse from the energy event that
has been digitized by the fast ADC.
•
Slow Threshold
– displays the current DC level representing the lower
level threshold of the slow discriminator. This value will vary when the
threshold mode is set to
Automatic
.
Horizontal Scale (µS)
This setting sets the full scale range in microseconds of the digital graph’s X-axis
for both plots. Note that as the scale increases, the capture resolution will
decrease. Resolution is maximum when the Horizontal Scale is set to its
minimum setting.
Shorter range is useful for close examinations of the signal processing; longer
ranges are useful when troubleshooting ground-loop signal noise issues.
