<blockquote> | |||
An improved delayed sweep system is disclosed for an oscilloscope having main and delayed sweeps. | |||
A trigger pickoff circuit has means for providing a pair of pre-selected trigger pickoff points on the delaying sweep so that delayed sweeps may be generated in accordance with the two points selected. | |||
An alternating display mode facilitates presentation of the delaying sweep and both delayed sweeps in a single display, with the relative time positions of both delayed sweeps appearing on the delaying sweep as a pair of intensified zones. | |||
Either delay time measurement between the sweep start and a point of interest on the display, or differential time measurement between two points of interest on the display may be made. | |||
Voltages proportional to the selected time measurement may be applied to a properly scaled digital voltmeter to provide a direct readout in units of time. | |||
