Part I - Advanced Examples

  1. Open Spectrum (click to download). Set the Frequency 2 and 3 to zero. Also change Amplitude 2 and 3 equal to zero. Change the Frequency bar and listen to the signal from the speaker. Pay attention to the signalís frequency as it is displayed.
  2. This is a very good LabVIEW program to measure Fourier transform of various input signals.


Part II - Practice

  1. Open This VI shows how you can generate a random number between 1 to 6. Note how this program is put together.
  2. Open the program. Understand how it operates. Then change this program such that you can change the TONE and its DURATION from the front panel. Hiont: You should use knobs. Show your VI to the instructor.
  3. Open the In a NEW vi use this module as a sub-vi. Use a knob to modify the frequency and a selector to change the signal type. Show your VI to the instructor.
  4. Open the Change the Square waveform to Sine waveform. Also, add an indicator such that you can monitor the frequency of the signal you are generating.


Part III - More Examples

  1. Here are some more examples you can do on your own to learn more about LabVIEW.
  2. Read about how to program National Instruments USB-6009 and USB-6008 multifunction I/O devices.
