Event List

The Event List Instrument type that is used to find certain events for analysis by evaluating a search condition. shows all value changes of the assigned signals. Events can be shown for Boolean signals As opposed to analog signal: a discrete signal for which exactly two specific values are defined. as well as for numeric, enumerations, and string signals. String signals are, for example, user comments during recording. For Boolean and numeric signals a rising respective falling edge icon is shown depending on an increasing respective decreasing physical value. For string and enumeration signals, only string values with an event icon are shown.

If the assigned signal changes, the content updates automatically. For example, the signal changes in the following cases:

• The assigned signal is a calculated signal and you modify the calculation formula. For more information, see Defining Calculated Signals.
• You replace the measure file that contains the signal or other signals that are used for calculating the assigned signal. For more information, see  To replace a measure file.
• You define a time offset. For more information, see Defining a Time Offset for a Measure File.

To see how you can use the Event List to navigate quickly between specific events and display these in an oscilloscope, watch our video Finding Events.

You can perform the following actions:

• To define the Event List properties
• To scroll the visible time range
• To navigate to the start or end of the time range
• To move the synchronization time stamp
• To show or hide header rows
• To reorder columns
• To change the decimals of the time column
• To delete a signal
• To filter a signal/ signals

To define the Event List properties

The complete set of configuration possibilities for this instrument is available in the Properties docking window. There, the tooltips provide a detailed description of the properties and their possible options.

1. Do one of the following:

   • In the instrument, click .

     or

   • Select the instrument and press Alt+Enter.

     or

   • In the instrument, right-click and select Properties in the context menu.

To scroll the visible time range

To quickly navigate to a specific time stamp, you can use the time slider Control used for navigating on the time axis, including zooming functionality.. For more information, see  Time Navigation and Synchronization. Alternatively, you can scroll by using the keyboard:

1. To move upwards, press the Page up or Cursor Up key.
2. To move downwards, press the Page Down or Cursor Down key.

To navigate to the start or end of the time range

1. To navigate to the start of the time range, press the Home key.
2. To navigate to the end of the time range, press the End key.

To move the synchronization time stamp

In synchronized mode, the synchronization time stamp is highlighted in the second row in blue. If the synchronization time stamp is located between the first two rows, a blue line is displayed between these rows. For more information, see Synchronizing Instruments.

1. To move the synchronization time stamp, double-click a row.

   or

2. Use the keyboard:
   1. To select a row above the current synchronization time stamp, press Alt+Cursor Up.
   2. To select a row below the current synchronization time stamp, press Alt+Cursor Down.

To show or hide header rows

To distinguish signals that have the same name but are coming from different devices or different rasters, you can display the device, raster, or unit.

1. In the toolbar, click or use the tab Instrument in the Properties Window.

   A list of the default header rows appears.

2. To show or hide a header row, select or clear the checkbox of the respective name in the list.

To reorder columns

1. Move a column by dragging its column header to the new position within the table header.

   A line between the columns appears to indicate the new position.

2. Release the mouse button.

To change the decimals of the time column

1. Mark the time column for which you want to change the number of decimal places.
2. In the toolbar, click one of the following icons:
   • To show more decimal places, click .
   • To show fewer decimal places, click .

To delete a signal

1. Right-click the signal name in the column header of the event list.

2. Select Remove Signal.

   Alternatively, select the signal name and press Del.

To filter a signal/ signals

From the amount of information, you can filter out the data that is relevant to you. Conditions can be defined that the values must then fulfill, the rows with the time stamps are thinned out and only those which fulfill these conditions are displayed.

1. Click the column.

2. Select from the conditions offered.

   Only one condition can be set per column.

3. Click Clear all or Clear to re-set all or merely one filter in a specific column.

Note
This only works out on rows that have a numerical value. You can display the signal again and filter it by numerical value. If there are several filters, a logical link with "and" is feasible. Merely the time rows for which both conditions are met remain. Signals including textual information cannot directly be filtered so far. No selection list is provided.

When filtering, the table always uses the interpolated mode. This means that cells for which the relevant signal has not provided a value are filled with the last available value.
