An accurate ramp and stair step source

This describes a method of producing extremely linear ramps or multiple steps of well defined amplitude waveforms by modifying a single step pulse. The basic circuit uses lengths of coaxial cables and resistors to transform a single step into two steps with in/out impedances matched to the cables and resistors. Multiple circuit sections can form multiple stair-steps or a ramp of sub-nanosecond to microsecond in length, with mV or kV amplitudes. Amplitudes and times are limited only by the coaxial cable and resistor maximum voltage capabilities and trimming lengths.
