Method and system for calibration of the deflection velocity and / or of the time dimension rod of the time base of a two coordinates - display device, in particular of an oscilloscope

摘要

A slewed-pulse display is provided for calibrating the time- base axis of an oscilloscope. In a repetitive-sweep display, the leading edges of incrementally delayed successive pulses are slewed across the display screen. Timing and linearity adjustments may be made in the time- base generator circuits so that a leading edge of a pulse is aligned with each vertically scribed graticule line overlaying the display area.
