ABSTRACT:
An engine analyzer having a dual-trace digital oscilloscope display provides a discrete waveform plot area for each trace and displays in each plot area a cursor array which may selectively include one or two vertical-line cursors which can be selectively moved one at a time horizontally along the plot area. The movements of the two cursor arrays can selectively be either synchronized or unsynchronized. The scope provides alphanumeric indications of the position of each cursor, the waveform value at the point where each cursor intersects the waveform. When two cursors are displayed on a trace the scope provides alphanumeric indications of the distance between the cursors and the difference between the waveform values at the points where the cursors intersect the waveform.
