Voltage Controlled Oscillator
The MOS-LAB 1004-T Oscillator Module is a signal controlled waveform generator. Sine, triangle, square, sawtooth, and pulse outputs are available simultaneously. In addition, five center-off miniature toggle switches allow any of these waveforms or their inverses to be selected to an additional output.
