Dynamic calibration of waveform recorders and oscilloscopes using pulse standards

Abstract

The current methods used to calibrate oscilloscopes are briefly discussed, and the problems associated with oscilloscope vertical channel bandwidth testing are illustrated. A method is presented for the complete and correct calibration of an oscilloscope voltage channel. A solution that involves measuring and digitizing pulse signals and an NIST-developed deconvolution algorithm is shown. An example of the calibration of the vertical channel of a 20-GHz sampling oscilloscope is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
