Abstract : A waveform sampler, for cooperation with a conventional sampling oscilloscope, has, as part of a bridge circuit, two Gallium Arsenide photoconductors mounted on a 50 ohm stripline. To sample an unknown electrical waveform traversing the stripline the electrical wave is optically strobed by illuminating the sampling GaAs photoconductor with pulses of light from a laser. To sample an unknown optical waveform the optical wave is focused on the sampling GaAs photoconductor and an electrical strobe signal is sent through the stripline.
