This circuit produces a square wave signal with the frequency determinated by R1 and C1. The upper limit for the frequency range is about 100 kHz, but other operacional amplifiers can be used for higher values. The power supply is single and the waveshape of the signal is shown by the oscilloscope. See the amplutude and time adjustments for this instrument. To change the frequency you can replace R1 by a 1 M ohm potentiometer in seris with a 10 k ohm resistor.
