Repetitive waveform high frequency, high precision digitizer

A digitizing technique for measuring high-speed phenomena with very high precision is described. A commercially available waveform digitizer using this method is shown to exhibit settling times of less than 5 ns to 0.1% and less than 10 ns to 0.01% after a voltage transition. Also, RMS measurements of sine waves up to 100 MHz show errors on the order of that obtained using a thermal transfer standard
