Abstract
A digital engine analyzer has an oscilloscope display screen operable in single-trace and dual-trace modes and in live and freeze modes, and having signal pickup leads for respectively acquiring different input signal waveforms from the engine and digitizing them for storage and display. When the freeze mode is entered, the last-displayed screen display format is frozen, and can then be reconfigured by the user by altering one or more of the number of traces, the signal plotted on each trace, the engine sweep of each trace, the scale and the scale offset for each trace and, in the case of a cylinder sweep, the displayed cylinder. In dual trace screen display formats, the user can also select for display on trace 2 a waveform pattern selected from a stored library of patterns.
