ABSTRACT:
A pulse generator provides a continuous train of electrical pulses of variable frequency, duration and amplitude. The pulse generator includes an adjustable frequency astable oscillator coupled to a monostable pulse generator. An isolation circuit isolates the output of the monostable pulse generator from loading effects to minimize output waveform jitter. A power amplifier receives the isolated pulse signal from the monostable pulse generator and provides output pulses of sufficient energy to simultaneously power continuous and capacitive electrical loads with minimal effect on the pulse generator output pulse waveshape.
