New Features in LabVIEW SignalExpress 3.0
Environment Enhancements
Operator Interface
The new operator interface lets you bind controls to step parameters and disable further editing of your project to ensure consistent results and further simplify user interaction. Optionally set a password to prevent users from being able to edit step settings.
Drag-and-Drop Layout Arrangement
Customize your workspace by dragging and dropping views. Any view, including the Project View, Channel View and Event Log, can be displayed as a floating window, docked to the side of the screen or displayed as a tab in center of the screen.
Channel View
The Channel View allows you to quickly and easily configure all of your hardware channels and shared variables. Additionally channel configurations can be exported to Microsoft Excel and any changes made to the resulting spreadsheet can be imported back into the project.
Enhanced Cursors
Cursors can now be linked to other cursors on the same display or between cursors. You can also export measurement values from the cursor legend to the Project View for use as inputs to step parameters.
Project Documentation enhancements
View as a printed page or web layout, resize any object, undo and new toolbar buttons make it easier than ever to report your data directly from SignalExpress.
More Flexible Features
Shared Variable support
Publish acquired data to shared variables for networked users to read or log data from other LabVIEW and LabVIEW Real-Time targets, including the new CompactRIO Scan Engine.
Configure Run Dialog
Configure your project to run continuously, for a set number of iterations or for a specified amount of time.
Sequence Step
The new Sequence Step allows you to pause the execution of steps to allow multiple steps in the same project to use the same hardware.
Improved Logging
Event Detection
Quickly locate the interesting points in your data by adding keystroke or signal-based events to your project. LabVIEW SignalExpress saves the events in the log file along with an annotation on the graph display.
New Start and Stop Conditions
New triggers, scheduled start times, holdoff and restart behavior allow you to capture just the data you need. Condition logic enables you to specify how SignalExpress processes multiple start or stop conditions.
More Alarm Actions
In addition to displaying a message or making a sound when an alarm occurs you now can generage a software trigger, create a snapshot or run a program.
New Features in LabVIEW SignalExpress 2.0
- Data Logging
- Use the integrated data logging tool to record, save, and analyze your measurements. You can record any step output. You also can analyze and process logged data by playing it through analysis steps.
- Read the LabVIEW SignalExpress data logging white paper to learn more
- Channel View
- The Channel View provides an integrated environment for viewing and configuring hardware channel information.
- DAQ Assistant Integration
- LabVIEW SignalExpress now supports full DAQ Assistant integration. The DAQ Assistant dialog boxes are fully integrated in the LabVIEW SignalExpress environment. When you install the DAQ Assistant, use the DAQmx Acquire and DAQmx Generate steps to acquire and generate signals from DAQ devices.
- Project Documentation View
- You can create project descriptions, display acquired data, or document your measurement results in the Project Documentation tab.
- View a 1 minute video on creating interactive reports
- New Data Viewers
- Several new data viewers, including tanks, thermometers and gauges, are available for viewing scalar and time-domain data. Right-click the Data View and select Switch to choose a display.
- Work Areas
- Use work areas to perform multiple LabVIEW SignalExpress operations from within the same project.
- New Steps
- Read Shared Variables step
- Statistics step
- Software Trigger step
- Step Improvements
- Time Averaging—The Time Averaging step now accepts scalar data as an input.
- Histogram—The Histogram step now accepts scalar data as an input.
- User step—The User step is now called the Run LabVIEW VI step. The Run LabVIEW VI step now supports LabVIEW 7.1 and later.
- Formula (Scalar)—The Formula (Scalar) step is now called the Formula step. The Formula step now accepts waveform data as an input.
- Limit Test—You now can perform actions on LabVIEW SignalExpress data depending on the result of the Limit Test step. Navigate to the Actions tab of the Limit Test configuration view to configure which actions LabVIEW SignalExpress takes when a signal fails or passes a limit test.
- Grouping
- You can use data grouping to analyze multiple data channels at once.
- Options Dialog Box
- Select Tools»Options to display the Options dialog box. Use the Options dialog box to configure various LabVIEW SignalExpress options.
- Snapshots
- Snapshots allow you to save a record of the current values of all step outputs in your project.
