I'm looking for a solution to a problem but have a couple of questions about oscilloscopes in general.
I have an intermittent problem with an automotive ECU. While driving the ECU shutsdown and requires the ignition to recycle. Its not the power supply (I don't think), it may be cam / crank pickups causing the problem, but I can't tell. (oh, the ECU has been replaced )
So what I THINK I need is an oscilloscope to measure signals into the ECU etc., but the problem is its intermittent.
How would I setup a unit to measure this, what would I need - What options are available (units etc.)
Also, where a given oscilloscope has a buffer size is this measured in bytes ? ie. 32K
And as such if the measurement resolution is 8 bits, can I store 32,000 entries in the DSO ?
Is this affected by the measurement cycle ie. are measurements / second fully adjustable.
Last question: What cycles would be recommended for a measurement that requires a reasonable resolution of 6 magnetic cranks sensor readings for each RPM (5500 RPM Max)
