SignalExpress Software Download. An interactive measurement program from National Instruments. With LabVIEW SignalExpress, measured values from hundreds of plug-in card and measuring device types can be recorded, analyzed and displayed quickly and without programming effort.
LabVIEW SignalExpress creates projects that capture, analyze, define, create, and display signals. For example, you can capture a signal with your computer’s plug-in cards, process it and output the resulting signal to other plug-in cards.
The steps available for creating projects depend on which wizards are installed. The creation of projects with wizard-specific steps is described in the description for the respective wizard.
LabVIEW SignalExpress includes steps for communicating with National Instruments hardware. You can also import LabVIEW VIs that exchange data with connected devices. In sweep mode, you can also make repeated measurements on a signal with different parameter values.
With the Sound and Vibration steps, you can interactively create applications for acoustic and vibration measurements. The Sound and Vibration Assistant is an extension of the LabVIEW SignalExpress program interface and contains all the functions of LabVIEW SignalExpress. If the Sound and Vibration Assistant is installed, the view in the Add Step menu is adjusted so that the most common steps for acoustic and vibration measurements are easier to find. See Sound and Vibration Steps for more information on using the Sound and Vibration Assistant.
SignalExpress Data View Tab Improvements
The following improvements have been made to the Data View tab :
- Display Properties — Use the Display Properties dialog box to set preferences for all types of displays. This dialog box was introduced to replace the Graph Properties: Waveform Graph dialog box in LabVIEW SignalExpress versions up to and including 2.5. The available settings for a display depend on the display format. The dialog box can contain Title, Format and Precision, Plots, Scales, Cursors, Signal Order, and Advanced pages. To display this Display Properties dialog boxclick the Properties button in the data view or right-click a display and select Properties from the context menu.
- Friendly Name — Ads are labeled by default. You can also use the Title page of the Ad Properties dialog box to change the name of an ad, and to show or hide an ad’s caption.
- Graph Palette — The Graph Palette was introduced to replace the graph zoom buttons. This palette is also displayed for graphs in the project documentation.
- Cursors Improvements — Cursors can be linked together on the same screen or on different screens. In addition, measured values can now be transferred from the cursor legend to the project view and used as input values for steps. By linking cursor measurement values with step parameters, input values for steps can be provided. You can also assign a threshold value and an area for peak value detection to each cursor in a display. Cursor settings are made on the Cursor page of the Display Properties dialog box.
SignalExpress Project view improvements
In LabVIEW SignalExpress 3.0, steps in the Project View are grouped into execution loops. An execution loop encloses a group of steps that have a data dependency between them. If a newly added step does not receive a signal from previous steps, it is presented with a new execution loop. Steps in different groups do not exchange signals with one another. Instead of execution loops, previous versions of LabVIEW SignalExpress included execution separators.
SignalExpress Channel view improvements
The following improvements have been made to the channel view:
- Environment Variables Mode — The Channel View allows you to see all of the available environment variables on the local computer and on the local network. To do this, select the Environment Variables option from the View pull-down menu in the upper part of the channel view. When activating the Capture option next to the name of an environment variable, a step of the type Query Environment Variables is automatically configured and inserted in the project view.
- Importing a Channel View from Excel — The contents of the Channel View can be exported to Microsoft Excel or imported from Microsoft Excel. With this function you can use a certain configuration of the channel view in several projects or edit the configuration data directly in Microsoft Excel and then import it again.
