Design and Performance of a Selectable-Rate Streak-Camera Deflection Ramp Generator

Altering the time base required physically changing the ramp generator. In this article a new method of generating the sweep deflection ramps is presented that permits changing the sweep rate by computer control without replacing the ramp generator. A logic level signal can now be used to change sweep rates without the need for invasive component changes. This new development permits fast and easy sweep rate changes for streak cameras in any location throughout the laboratory, especially in low accessibility locations such as clean rooms and high-power-laser environments.
