Review of inexpensive USB scope - DSO-2150 USB
Five years ago, I designed an engine controller for automotive engines (powered by natural gas) used in oil fields to run the actual pumps.
I own a couple very nice scopes but you don't find 110v in the middle of a cow pasture - so I purchased a USB scope from china - since it would work with a lap top.
Project went on hold and I through the USB scope (unopened) in the closet.
I started building up the 24 channel controller board I designed and figured it would be a good test for this scope instead of digging out my good scopes.
I populated the 5v supply and Zero-Crossing (ZC) detector before populating the cpu circuitry (still checking the board - first time in use).
I've attached a shot of the ZC pulse so you can see what this little scopes does. I'm impressed so far - it's a 60mhz bandwidth, 2 channel scope.
I googled them and found today they are priced $200 +- $15 depending on where you go.
If anyone is looking for an inexpensive scope to use in circuit development - I would say this one might be a nice choice.
Tried to load the pic as an Image - but the web site does not appear to be taking images (sits for 10+ minutes saying "waiting on ....".
I put the pic on my site with a link to it below.
