Dear Automotive Picoscope users, any thoughts on accomplishing my goal (or coming close) would be appreciated.
I am collecting the pieces required to measure gas pressure in the ducts of an engine running at 8,000 RPM.
I am hoping that a Picoscope of some kind can complete the hardware collection of my system.
I would like to measure at each degree of crankshaft rotation if possible.
(8,000(RPM)/60 seconds per minute) * 360 (degrees per revolution)
= 48000 samples per second.
I need to trigger the start of a cycle each camshaft revolution. I hope that I can use a pick-up or an encoder for that.
I have 3 sensors to collect data from (they each have amplifiers).
I would be interested to have more sensors if possible, 4 would be good, but 8 would be great unless it multiplied the cost (this is a personal hobby project).
I will want to display the collected data in a graph.
If there is an application that does what I want easily, I might use it.
I expect that I will prefer to collect the data from a text file and graph it with an application that I will write.
I wonder if there is a way to graph the data in real time (maybe in coarser frequency).
Can you tell me if there is a PicoScope that can do this, if so what model?
I am looking at the 3000 series scopes but do not have a good enough understanding of the technical specs to know if it is capable of supporting this project.
I don't believe there's an 8 channel scope, so it seems that your limit is going to be 4 inputs.
The Pico Scope can handle your required sample rate a thousand times over, what I tought would be your issue would be the response time of your sensors, if the response time of all of your sensors are 0.20 of a milli second or faster then you are covered.
The pico files can be converted into CSV files if you wanted to graph it in another application like excel
It is a T&M scope so does not run the Automotive software and is a 50Volt max input so will need to be used with care but as the early Pico Automotive scopes were a 20Volt max input .......!
What the OP is describing is not so much Automotive Diagnostics as Data logging / Analysis so really it is more in the realms of the T&M boys and girls; there forum is Here https://www.picotech.com/support/
The T&M software is perfectly suited to all manner of analysis and will talk to numerous software applications.
*****EDIT*****
I see that the OP has posted in the T&M forum and has been advise to contact support with more details.
