Numerical to analog conversion. A high frequency converter tube
Abstract
A breadboard model of a high frequency converter tube having opposed electron guns sweeping a silicon diode mosaic target is presented. An input beam energy of 8 keV which allows signals to be registered at a frequency of 150 MHz with a resolution of 400 television lines at the target diameter is examined. The output signal is video and is monitored on a television display. Results indicate that after optimizing the tube/target/tube design it is possible to measure signals at a frequency of 1 GHz.
