User Interface (Windows version illustrated)


All commands can be accessed from the menu bar. Many of the more commonly used commands can also be accessed from the tool bar. A detailed discussion of each particular menu bar command can be found by clicking on the Menubar link above.


For convenience, many of the more commonly used commands can be accessed from the tool bar. When commands are accessed from the toolbar, the resulting behavior is identical to the behavior of the corresponding menu bar item.


Tooltips are small pop-up windows that appear when the mouse hovers over a toolbar tool. They provide a text reminder of the menubar command that will be executed by the tool.

User Hints

Text appears in this field whenever the mouse hovers over a toolbar tool or menubar command to give a brief description of the purpose of the associated command. When the mouse is in the Signal Display Window, the location of any markers will be displayed in the User Hints area.

Hardware Status

Text appears in this field to indicate the status of the ChronoVu hardware, or the status of various software operations.

Signal Name Window

The signal names associated with each channel are displayed in this window.  Signal names, colors, and visibility can be specified by using the Acquisition Setup command or the Bus Analysis Setup command.

Signal Display Window

This is the area where the acquired signal data is displayed.The view in this window can be scrolled and zoomed for convenient viewing, or analyzed by setting the appropriate bus specifications on the Bus Setup menus.


Up to 10 bookmarks can be placed in the Signal Display Menu. Bookmarks are used to mark locations to which you will need to return. Once a bookmark is placed, the viewing window can be instantly panned back to the marked location using the Bookmark menu which is accessible from the menu bar, the toolbar, or by keyboard shortcuts. For detailed instructions, on using bookmarks, click on the Bookmarks link above.


When the left or right mouse buttons are clicked in the Signal Display Window, an “L” or “R” marker will be placed at the indicated location.The exact location of any placed markers, as well as the spacing between the markers, will be displayed in the User Hints area whenever the mouse is located in the Signal Display Window.Markers can be removed by double clicking the appropriate (left or right) button in the Signal Display Window.(Note that markers should ideally be placed when the Signal Display Window is at the maximum zoom level in order to insure the highest marker placement accuracy).


A variety of keyboard shortcuts have been defined to change the scale or location along the time axis. The mouse wheel will pan the view along the time axis. If the Shift key on the keyboard is pressed, the mouse wheel will zoom the view without changing the location along the time axis. The keyboard arrow keys can be used to pan right or left, and the Home and End keys will pan to the front or end of the dataset respectively. The + and – keys will zoom in or out. If bookmarks have been set, the number keys will pan to the appropriate bookmark. Shifted number keys will set the appropriate bookmark.

Note about shifted keys: The shifted number-pad keys are defined as arrows, Home, End, etc. on many keyboards, so only the normal number keys, near the top of the keyboard, are trustworthy for setting bookmarks. The _ and = keys are defined as Zoom keys so that the + and – keys will work on most keyboards whether they are shifted on not.

Note to Mac Users: Shifted mouse wheel will not zoom on some Macs with some mice, however two-finger vertical swipe will pan and shifted two-finger vertical swipe will zoom on Mac laptops.
