Marker mode. ‘Marker’ mode is entered by clicking the icon on the
Palette Bar or by choosing Edit | Marker Select from the Menu Bar.
This mode automatically enables the X and Y markers. Selecting either X
or Y markers (from the Edit Menu or with icons) also causes the cursor to
change to ‘marker’ mode. Move the markers using a click and drag
motion, or, for fine adjustment, the arrow keys.
While you are in ‘marker’ mode, the Status Bar reflects the location of the
X or Y marker pairs as they are positioned in the waveform edit window
and the difference between them. To exit this mode, click the ‘marker’
icon again. This disables the markers and enters the ‘edit select’ mode.
Clicking the ‘edit select’ icon will exit ‘marker’ mode and leave the
markers enabled.
Zoom
There are six zoom levels available. In the normal viewing mode (fully
zoomed out) one pixel of the screen equals 32 waveform data points.
Zooming in decreases the number of points equal to one pixel in multiples
of two (e.g. 32, 16, 8, 4, 2, 1). Zooming can be performed in the following
ways:
To zoom into part of a waveform, choose View | Zoom from the Menu
Bar or click the Zoom icon. The cursor will change to a magnifying glass.
Click and drag your mouse to define the area to zoom into. When you
release the mouse button, the selected area will be displayed in the active
waveform window. This process can be repeated until you are fully
zoomed in and one pixel equals one data point.
To zoom in one level at a time, choose View | Zoom In from the Menu
Bar or click the Zoom In icon. You can zoom in until you reach the level
where one pixel equals one data point.
Click the Zoom Out icon or choose View | Zoom Out from the Menu Bar
to zoom out one level at a time. You can zoom out until the entire
waveform is displayed. If you wish to zoom out and display the waveform
in one step, choosing View | View All will fit the entire waveform into
the waveform edit window.
The zoom locator box in the Wave View window outlines the
portion of the waveform currently displayed in the waveform
edit window. This box changes as you zoom in and out and can
be moved by clicking and dragging it.
