Exporting Captured Data

DigiView's captured data can be exported to an ASCII file for further analysis or documenting purposes. DigiView provides three export methods to chose from, with each method having a few unique features.

• Export All Signals - This export method can be selected from the File menu and provides a means of exporting the raw data of all defined signals. The available options let you chose which signals to export, time format, numerical format, field separator, inclusion of line numbers, inclusion of a timestamp and whether to use compression.
• Export List Data - This export method can be selected from the File menu or directly from a List Window's menu. List Exports export the decoded data of higher level signals (such as I2C), and will have a slightly different set of options that are specific to each signal type.
• Export Table Data - This export method can be selected from the File menu or directly from a Table Window's menu. Table Exports provide all the same options as the "Export All" function, but will automatically include all columns of the table. This means you will not have to select which signals to export, plus all channels of any signals that are "expanded" will also be included in the export. This is the only export method that will export expanded channels.

Properties common to all three export methods

Export To - At the top of each export dialog, the file name and path for the export file will be displayed. To change the name or location, chose the button to the right of the filename. You can chose any valid storage device for your system including a Network Drive, Floppy Disk, FLASH Memory, and etc.

Time Range - Select the Starting time and Ending time of the data to export. You can select from several predefined time points (i.e. Waveform View 1 Start, Trigger, Marker X, etc) or select Custom to manually enter the time.

Estimated Free Disk Space - The available space of the export destination is calculated and displayed here. The available space will be calculated whenever the destination changes. While the export is in progress, this will be updated to keep you informed of remaining space. If the available space becomes too small for the remaining portion of the export, then the export will automatically finish without exporting the rest of the data.

Required Disk Space - The amount of disk space required to hold the exported data will be displayed here. Since all storage devices require a minimum amount of space to hold a file, the minimum file size will be shown if the exported data is smaller. If the export size is very large, the background color of this display will turn to yellow. If the export size exceeds the available space on the storage device, the background color will turn to red and the export prevented from being performed. The export size will be calculated whenever any option or the destination changes.

Progress indicator - The lower left portion of the Export dialog will display the progress of the export. The progress display will indicate the number of bytes already exported, the percentage of the data already exported and the number of bytes per second being written to the storage device.

Abort Button - The export can be canceled at any time by selecting the Abort button. All data exported up to the point of cancellation will be available in the exported file.

Close Button - To exit the Export window, chose this button. If an export is in progress, the export will be canceled automatically.

Export Button - After selecting the desired export options, chose this button to begin the export. This button will be disabled while an export is in progress or the export size is being calculated.
