CHAPTER 3 ANALYZING AND SAVING A SIGNAL LabVIEW includes a set of Express VIs that help you analyze signals. This chapter teaches you how to use LabVIEW to perform a basic analysis of a signal and how to save the analyzed data to a file. 📌 Note The exercises in this chapter use Express VIs that are available only in the LabVIEW Full and Professional Development Systems. BUILDING AN ANALYSIS VI In the following exercises, you will build a VI that generates a signal, filters the signal, indicates if the signal exceeds a certain limit, and records the data. After you complete the exercises, the front panel of the VI will look similar to the front panel in Figure 3-1. Figure 3.1 Front Panel of the Save Data VI Modifying a VI Created from a Template Complete the following steps to create a VI that generates, analyzes, and displays a signal. 1. In the Getting Started window, click New to display the New dialog box. 2. From the Create New list, select...
CHAPTER 2 CUSTOMIZING A VI You can choose one of many LabVIEW template VIs to use as a starting point when building VIs. However, sometimes you need to build a VI for which a template is not available. This chapter teaches you how to build and customize a VI without using a template. BUILDING A VI FROM A BLANK VI In the following exercises, you will open a blank VI and add structures and Express VIs to the block diagram to build a new VI. You will build a VI that generates a signal, reduces the number of samples in the signal, and displays the resulting data in a front panel table. After you complete the exercises, the front panel of the VI will look similar to the front panel in Figure 2-1. Figure 2.1 Front Panel of the Reduce Samples VI OPENING A BLANK VI If no template is available for the VI you want to build, you can start with a blank VI and add Express VIs to accomplish a specific task. Complete the following steps to open a blank V...
