Analog Electronics with LabVIEW®

PA.5. Observing the Oscilloscope Output Graph

To run the oscilloscope of Fig. A.14, in the project library, ProjectA.llb, open VI FG_A.vi. (This VI can also conveniently be opened from the Diagram of a new LabVIEW VI.) Then under the Browse menu (from the Front Panel of FG_A.vi) go to Show VI Hierarchy. Locate the icon for OscilloscopeA.vi and Double Click to open the VI. Run FG_A.vi at various values of Vs (Vac peak signal out) and VDCout and observe the combination waveform output in OscilloscopeA.vi. The limit setting is 10 V. The function generator VI, FG_A.vi, is discussed in a following section.
