A simple electrical stroboscope having a rise time of 6 × 10-11 seconds and a 6-db bandwidth of 5.5 kmc is described. Oscillograms showing 160-mc square waves and 640 million pulses per second are shown. These waveforms display rise times as fast as 2 × 10-10 seconds. Instrumentation includes a strobe-pulse generator, a coaxial gate using a gallium-arsenide point-contact crystal, suitable wide-band coaxial attenuators, a low-pass integrating filter and a low-frequency oscilloscope.
