Oscilloscope General Controls
The oscilloscope general controls appear at the bottom
left of the oscilloscope window. From here you can con-
trol such aspect as the time base, triggering modes and
memory used for the captured data.
Time Base
The required time base is selected using the up/down
scale buttons either side of the current time base scale
text box (left side button decreases the scale, and the
right side button increases the scale value.) The value
selected is the time per grid division on the display.
If the time base is greater than a predefined value, then the data is retrieved
from the controller in sections (as opposed to retrieving a compete trace of data
at one time.) These sections of data are plotted on the display as they are
received, and the last point plotted is seen as a white spot.
After the oscilloscope has finished running and a trace has been displayed, the
time base scale may be changed to view the trace with respect to different hori-
zontal time scales. If the time base scale is reduced, a section of the trace can be
viewed in greater detail, with access provided to the complete trace by moving
the horizontal scrollbar.
Horizontal scrollbar
Once the oscilloscope has finished running and displayed
the trace of the recorded data, if the time base is
changed to a faster value, only part of the trace is dis-
played. The remainder can be viewed by moving the
thumb box on the horizontal scrollbar.
Additionally, if the oscilloscope is configured to record both motion parameters
and plot table data, then the number of points plotted across the display can be
determined by the motion parameter. If there are additional table points not vis-
ible, these can be brought into view by scrolling the table trace using the hori-
zontal scrollbar. The motion parameter trace does not move.
