    Hi All,

    Does anyone manufacture a low frequency, Hi voltage output symmetrical square wave generator? I am looking for a unit that has variable frequencys in the range of 1 HZ to 100HZ or better. The variable output peak to peak voltage range should be better than 30 volts. Prefer a VARIABLE 50 volts or more peak to peak output.

    If a older unit is available somewhere I would like to know the model and manufacturer. If not --is a circuit available that I can use to build the unit.

    The power source for the generator would be common 120volt AC house voltage.

    All help appreciated.

    It would be better to design an oscillator with the max P-P output, then attenuate this down. As a starting point you could combine these two ideas.

    As for power source, you can buy or build a 50VDC unit. Be careful though, there is enough voltage here both on the square wave and the DC power to kill or injure.
