Abstract
An apparatus for sampling, analyzing and displaying an electrical signal as disclosed having a good signal-to-noise ratio and high resolution. The apparatus includes a light pulse source for emitting a light pulse toward the electro-optical surface of a photoelectron sampling tube which in turn emits a photoelectron pulse after receiving the light pulse. The emitted photoelectron pulse is then modulated by a signal to be measured and is accelerated to an anode which may comprise a display for displaying the wave form of the electrical signal as a two-dimensional image.
