ABSTRACT:
An engine analyzer has a dual-trace display screen, a waveform acquisition means for obtaining analog waveforms from an associated engine and digitizing them, a memory for storing digitized waveform data and a processor for controlling the operation of the memory and the display. The display is operable in live and freeze modes. The displays on the two traces of the display screen are normally synchronized but, in freeze display mode, the user may selectively deactivate the synchronization.
