Logging a Signal

Complete the following steps to create a log of a specified signal.

1. Place the Create Analog Signal step in the Project View.
2. In the Signal type pull-down menu, select Noise Signal.
3. If the Recording Options tab is not visible, select View»Recording Options to display the tab and the data logging configuration options.
4. Select the Signal Selection option in the Category list to display the Signal selection page. The Signal selection page displays the signals that are available to log. Place a checkmark in the checkbox next to the white Gaussian noise signal.
   
   When you select to record the signal, the Record button on the toolbar changes to the Record While Running button. When the Record While Running button is pressed, you can press the Run button to log the selected signal.
5. Select the Log Summary option in the Category list to display the Log Summary page. Specify the name of the log in the Log title text box and provide a description of the log in the Log description text box.
6. Click the Run button on the toolbar to begin logging the signal.

Note  Changing the configuration of a LabVIEW SignalExpress project during a data logging operation stops the current data logging operation.

7. When you are ready to stop logging the signal, click the Stop button on the toolbar.

Note  You also can configure logging to start and stop according to user-defined conditions. Use the Start Conditions page to configure logging start conditions and the Stop Conditions page to configure logging stop conditions.

The logged signal appears in the Logged Data window. To view a logged signal, drag the logged signal to the Data View. You also can analyze the logged signal using analysis steps by switching to the Playback work area to process a specific log.
