EG-50 Audio Driver

A digital set sine wave oscillator with an audio amplifier through the frequency range of 10 Hz to 10 kHz. On the low end of the frequency range the readout is multiplied by 10x so that the resolution is 0.1 Hz. The output will drive low impedance loads such as the EG-52 Electromechanical Driver. Frequency is easily set by a three-turn potentiometer on the front panel. A pair of jacks on the rear panel provides a square wave output to synchronize an oscilloscope, so the signal may be easily viewed without jitter on the simplest oscilloscopes.

 EG-52 Electromechanical Driver

The Electromechanical Driver converts the electrical output of the EG-50 Audio Driver into linear motion. It produces variable frequency and amplitude linear motion drive for all manner of harmonic motion experiments. It drives Chladni Plates, Sonometers, stretched strings, as well as many other vibration experiments. It can be powered by the EG-01 Function Generator, but with smaller amplitude.
