In this section, you will learn about the LabVIEW environment.

When you launch LabVIEW, the navigation dialog box appears that includes introductory material and common commands.

LabVIEW Dialog Box

The LabVIEW dialog box includes the following components:

  • A menu with standard items such as File>>Exit .
  • A set of buttons for creating and opening VIs, configuring data acquisition devices, and finding helpful information.
    • Click the New button to create a new VI. Click the arrow on the New button to choose to open a blank VI or to open the New dialog box.
    • Click the Open button to open an existing VI. Click the arrow on the Open button to open recent files.
    • Click the Configure button to configure your data acquisition devices. Click the arrow on the Configure button to configure LabVIEW.
    • Click the Help button to launch the LabVIEW Help . Click the arrow on the Help button for other Help options, including the NI Example Finder .

Creating and saving a vi

When you click the New button in the LabVIEW dialog box, the New dialog box appears. You also can select File>>New to display this dialog box. When you select a template in the Create new list, previews of the VI appear in the Front panel preview and the Block diagram preview sections, and a description of the template appears in the Description section. shows the New dialog box and the SubVI with Error Handling VI template.

New Dialog Box

Click the OK button to open the template. You also can double-click the name of the template VI in the Create new list to open the template. If no template is available for the task you want to create, you canstart with a blank VI and create a VI to accomplish the specific task. In the LabVIEW dialog box, click the arrow on the New button and select Blank VI from the shortcut menu or press the Ctrl-N keys to open a blank VI.

You also can open a blank VI by selecting Blank VI from the Create new list in the New dialog box or by selecting File>>New VI .

Open/templates

Use the New dialog box to create different components in LabVIEW to help you build an application. Youcan start with a blank VI to write a VI from scratch, or start with a template to simplify the programming. The New dialog box includes the following components:

  • Create new

    Displays templates you can use to start building VIs and other LabVIEW documents. Selectfrom the following templates and click the OK button to start building a VI or other LabVIEW document.

    • Blank vi

      Opens a blank front panel and blank block diagram.

    • Vi from template

      Opens a front panel and block diagram with components you need to builddifferent types of VIs.

    • Other document types

      Opens the tools you use to build other LabVIEW objects.

  • Browse for template

    Displays the Browse dialog box so you can navigate to a VI, control, or template. If you previously have browsedfor and selected a template from this dialog box, use the pull-down menu of the Browse button to select a template to reopen it.

  • Front panel preview

    Displays the front panel for the VI template you selected in the Create new list.

  • Block diagram preview

    Displays the block diagram for the VI template you selected in the Create new list.

  • Description

    Displays a description of the template you selected in the Create new list if the template includes a description.

Questions & Answers

A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?

Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
