Abstract
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.
