Pull-Down Menus
File – The File pull-down menu consists of a selection to exit the Scope display.
Edit – The Edit pull-down menu contains a selection labeled, “Display.” Clicking “Display” brings up an
Options dialog box for viewing or changing the display preferences. This is discussed in the following section.
Scroll Bars
DaqView Scope makes use of two scroll bars, each of which applies to specific display types. We will refer to the
bars as “upper” and “lower.” The two bars will not be visible at the same time for a given display.
The upper scroll bar appears at the upper right of the display when using
Filter, Spectrum, Frequency Transform or Windowing charts. For these
displays the acquisition data is separated into custom block sizes, as set in the
display Options dialog box in the Scans per Block field. When a block is being displayed only that specific block
will be visible on the display. The other blocks will not show data until the scroll bar is used to select them. The
leftmost side of this scroll bar displays the first block. The rightmost side of the scrollbar displays the last block. A
block identifier resides just to the right of the upper scroll bar.
The lower scroll bar is located directly beneath the display and runs the entire
length of the display. This bar is not visible for Filter, Spectrum, Frequency
Transform and Windowing charts. When the bar applies, you can use the slider to efficiently scroll through data.
With the slider located at the far left, the earliest data points from the acquisition are displayed. As you move the
slider right, later data points are displayed.
Changing Display Parameters
To make a global change to the appearance of the
scope displays, i.e., changes which affect every
scope on every display page, select “Display” from
the Scope window’s Edit pull-down menu. An
Options dialog box will appear with the “Display
Preferences” tab dominant (following figure). A
second way to access the Display Preferences tab is
to click the button for a scope
(button 17), then after the Options Dialog Box
opens, click on the Display Preferences tab.
