If it's not really about tuning or wiring. Then it belongs in here.
Looking for one to have in my shed as some sensors are impossible to test using multi-meter.
My priorities are:
1. Relatively cheap.
2. Less features. I only need to see wave and that's it.
3. Portability and small dimensions.
I will give a couple of suggestions:
1. Go for at least two channels if you can - it is often necessary for instance to see something change in relation to something else - such as cam position referenced to crank position.
2. Avoid the really cheap Hanteks such as 6022 and 1008, they really are crap. Their higher-end ones seem better.
3. You typically dont need anything too fast for most automotive testing ~5MHz. Good memory depth is nice to have though (length of recording it can do).
4. I have never used one of the "DSO Nano" type things but their interface looks pretty cumbersome.
I have played with quite a few USB and desktop scopes at different jobs. Here's some that I think are very good low cost options:
Picoscope 2204A ~USD$120.
Perytech DSO2100 ~USD$89.
Adam, truly great insights to start from. That's exactly an answer I've been looking for. Will give a glance to options mentioned as well.
+1 for Picoscope. Had mine for over a decade.
I really like my 4 channel Micsig. Picoscopes are great but I generally would prefer to have a stand alone display.
