Diagnostic Manual, Engines, Volume 1
Diagnosis - Oscilloscope
General information
Sample digital oscilloscope patterns are shown on the following pages. The Bear and Sun engine analyzers feature a memory with a manual display freeze. The sample oscilloscope display patterns should be compared to those of the test and adjustment equipment. However, the same test depth is not available since analog instruments can not store data.
The ignition oscilloscope can perform the following functions:
 Parade display,
Raster display,
Single display,
Switching from time and voltage ranges.
The displays listed can be stored, stopped and printed out individually.
In addition to the high voltage displays in the kV range, it is also possible to record signal displays in the low voltage range, for example, signals from sensors with 100 % or millisecond time basis.
Refer to page 50/1 for additional signal checks.
