Oscilloscope
In general, an oscilloscope is used to measure voltage over time. However, the oscilloscope displays a rel-
ative and un-calibrated value. After obtaining the measurement time, frequency can be determined.
By clicking on the graph, the display will be paused and measurement cursors appear for both axis.
Several Color schemes are available through the right-click menu.
The Trigger Mode option allows the real-time
oscilloscope to trigger on the Positive or the
Negative slope or to be switched Off.
The Trigger Level option allows conventional
level driven triggering to be set. The un-
calibrated input voltage range is from +99%
to –99%.
