03 Configuration

A configuration defines how to present signals. The configurations are stored within the eclipse preferences store.

What is a viewer Configuration?

A configuration describes how signals are presented. There are multiple different configurations available in the viewer which can be used to personalize the presentation of the signals.

The viewer shows the different configurations within a hierarchic structure. Displayed within this structure there are elements representing single signals and folders that pool multiple specific signals.

The configuration itself does not contain signal data, but how it is shown. It contains the settings of color, name, type of diagram (line graph, vector diagram etc.) and the way the data is represented (decimal representation, hexadecimal notation etc.)

How to create a new configuration

If you open a wave file with impulse and there is no suitable configuration available that has previously been used, the viewer automatically opens the configuration dialogue. The same dialogue can be opened with the Add new configuration button. In the opened window you can now add a name, a description and select one of the three possible configuration settings: "Empty configuration", "Create a hierarchy of all signals and scopes" and "Add a flat list of all signals".

  • Empty configuration
  • Create a hierarchy of all signals and scopes: generates a "copy" of the record file which shows the signals and scopes one-on-one
  • Add a flat list of all signals: all signals are taken from the record file and displayed one below another without any hierarchy

Next to the Add a new configuration button is a pull down menu which contains further options for the configurations. You can clone, edit and delete configurations.

How to modify configurations – add, remove, reorder, edit and resize elements


You can add single or multiple elements to the hierarchic structure by opening the context menu of the configuration with a right mouseclick. If you click add you can choose between adding a folder or single signals. You can also add elements with drag and drop from the signal area.


To remove elements you again open the context menu and click delete or mark the element/s you want to remove and press the delete key.


You can reorder all elements by marking and moving them with the mouse. You can also add elements to folders.


You can edit an existing configuration by opening the edit dialogue with the context menu or by double-clicking the element whose configuration you want to change. In the window you can find the name, the description and the signal in the upper left corner. Underneath appear different kinds of modulations depending on which kind of signal the configuration is for. They are meant for interpretation purposes. In the upper right corner you can change the color in which the element is displayed within the diagram. Some default colors are set but you can add your own personalized colors by choosing them with the icon next to the default colors. You can also change the color of an element directly with the context menu if you choose the option Set color. Underneath the colors you can find the types of diagram, again you will find different ones depending on which signal the configuration is for. Possible diagrams are: Logic, Vector, Line, Transaction or Event. Under this you find three additional configurations. First is the configuration (style) of the respective diagram. Second is the value column which defines how the current value is shown. Third are the markers with which you can tag certain positions (values) within the diagram. In the editing dialogue you can chose how these markers are shown. All changes you make are directly presented in the diagram. Furthermore you can edit the upper element and the folders. The process used is the same as for single elements. You open the context menu and afterwards the editing window.


Elements are resized when you mark one or more and move the mouse to the left. The cursor then changes to an arrow with two ends and you can enlarge or shrink the size of the element and its illustration within the diagram.

Switch between multiple configurations

When you open a record file in the viewer eclipse will automatically chose the most suitable configuration using the signal names and paths within the configuration. If more than one configuration is found for the record the first one will be used.

Impulse remembers the configurations used for a specific wave file and if you open it again, the previous configurations will be selected.

You can use an unlimited number of configurations for a wave file. The upper right button in the toolbar is used to switch between different configurations. The more you work with Impulse the more configurations will be listed there. To make it easier to find a fitting configuration you can use the filter button. The process of filtering is similar to the one that is used when the viewer is started and you get the most fitting configurations for your file.


To store you configurations you use the button Store Configuration Preferences in the toolbar. You can use the pull down menu to either save the changes you made for your configuration or reset the configuration.

All configurations are stored in the eclipse preferences store. You can find this in the upper left toolbar under Window –> Preferences. On the right side of the opened window you find impulse and the configuration store.
