The 4024 is an oscillator from Krohn Hite. An electronic oscillator is a circuit that converts direct current to an alternating current signal. Oscillators generate a periodic electronic signal, often in the form of sine or square waves. Engineers use oscillators on a variety of electronic devices.
The Krohn-Hite 4024 Audio Oscillator is a general purpose oscillator that produces sine and square waves simulteously from 0.001 Hz to 100 kHz with 125 mw of power into 200-ohms or 600-ohms. Frequency calibration is within ±0.5% and push-button tuning permits ±0.1% frequency repeatability.
