I need one to install a piggyback fuel controller. I don't really know how to use one but I only need it for looking at the basic waveform from sensors output and to make sure all the connections have clean power.

let me know if you can help

When do you need to use one?

I work for $400/hr

What I meant was that if someone owns one and wanted to help me then that would be cool. I actually found one on ebay cheap and ordered it so I can take my time to figure it out. All I need to do is determine sensor wave form from sensor outputs so I can set up the piggyback. I don't need to do any measurements just use it to make sure I have a clean noiseless ground clean power and check basic sensor function.

you don't need to be a computer expert to check email so I don't think it will be hard for me to use the basic functionality of a oscilloscope. I'll read the manual and do a little research online.
