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
