Engine Analyzers, General Info
Engine analyzers, also known as engine performance testers, were first developed in the 1960s to help tune and troubleshoot gasoline-fueled automotive engines.
The engines of the time had manually-adjustable ignition (spark) timing, and required frequent repair, which necessitated a variety of information.
These engine analyzers were large (often refrigerator-sized), completely analog units, and could read battery voltage, coil dwell time, engine RPM, peak voltage, and some could display the spark waveform on a cathode ray tube (CRT) display.
Specialized ignition scopes also became quite popular, and provided a set of ignition-specific features, including a “parade pattern”, which shows the waveforms from all spark plug wires simultaneously, allowing for easy comparison.
