Snapshots

Snapshots allow you to save a record of the current values of any signal in your project. You can view snapshot values on the Data View tab. You also can save these values to file or run them through analysis steps. You can use snapshots to compare data within the same project. For example, you can acquire data and create a snapshot of the data when the acquisition task is complete. Complete a new acquisition task with different settings and create another snapshot of the data after you complete the acquisition task. Drag each of the snapshots to the Data View tab to view and compare the data.

Select Operate»Create Snapshot to open the Create Snapshot dialog box. Use this dialog box to select the signals to include in the snapshot, and click the OK button to close the dialog box and create a snapshot of the signals you select. The snapshot appears in the Logged Data window. In the Logged Data window, expand the snapshot and right-click a signal in the snapshot to display a shortcut menu with various options, such as saving the snapshot of that signal to a text file and/or sending the signal snapshot data to an analysis step.

LabVIEW SignalExpress automatically saves snapshot data in the project file. You also can import snapshots from another project. Select File»Import»Snapshots From Another Project to select the project file from which you want to import snapshots.
