I’ve always wanted to get an oscilloscope as I feel it can be a handy tool in diagnosing engine running problems, especially with newer fuel injected cars, as the various sensors and controls aren’t simply on or off switches but pulse at very high rates.


Obviously the more channels the unit has, the better (although cost goes up considerably with each channel added). My question is, what minimum frequency should the unit be capable of measuring in order to evaluate say, a fuel injector or ignition coil circuit at near max RPM? 10,000Hz? 100,000Hz?
