The Sine Wave Generator is an excellent tool for generating waves with speakers or wave drivers. It allows both the frequency (1-800 Hz) and amplitude of the sine wave output to be varied. Both fine and coarse frequency controls are included and the digital display features a 0.1 Hz resolution. In addition, the generator can "learn" the fundamental frequency for a particular configuration. Students can observe the quantum nature of standing wave patterns as the Sine Wave Generator jumps from one resonant frequency to the next.
