Pulse generator based on commercially available digital circuitry

The circuitry of a low cost pulse generator based on a commercially available digital integrated circuit is presented. The circuit produces 'rectangular' pulses of amplitude 0.77 V and width 362 ps at half amplitude, and 0.688 V peak-to-peak monocycle pulses with a -10 dB bandwidth of 1.2787 GHz (0.1191 to -1.3978 GHz).
