This affordable alternative to the advanced Function Generator PI-8127 covers the most common experiments.
The function generator is operated with three buttons: Waveform, Frequency, and Amplitude. There is a single output, provided with 4 mm safety sockets. The frequency is displayed on the LCD display.
The output can easily drive a speaker or vibrator with ample amplitude for resonance. The frequency range extends well beyond the audible range. The lowest frequencies are suitable for slow-motion AC experiments.
